This is a totally a real world test... Kudos for your effort! I had a 2019 5.3 RST towed a 6k travel trailer all over NM,CO,WY,AZ .. it worked but damn the mileage sucked and if the wind blew.. I just wanted to pull over. Traded for a 2023 LTZ 3.0 ... different thing all together.. I get crazy mileage without the trailer 25 town, 28 highway and my 5.3 was around 9.5 pulling the trailer ( and I never checked it by hand and I'm saying that computer was a lying mofo), the 3.0 duramax 12.5 towing same trailer and actually better when hand calculated. Kudos to GM for erroring on the low side with the computer with this new truck. Oh.. I did put sumo springs on the new truck .. huge difference when towing as far a stability. Thanks for this great video.
Thank you, I’m glad you liked it! That’s awesome to hear a comparison with the 5.3 and that the LZ0 is working out for you much better.
I have a AT4 with the LZO and tow a 7,000lb travel trailer in California. I average between 12-13mpg while towing. Worst mileage I’ve had was 10.5 mpg towing steep grades. California has a wide mix of terrain from flat to very steep almost everywhere you go. Unladen I get 25-27mpg hwy and 21-23 combined. I’m not easy on the throttle either.
That’s a lot better economy than you’ll get from the gas engines
Love my 21 Sierra SLT 3.0. I installed a set of timbrens to help with the squat. On an 18 hour trip into Canada pulling a 3,000lb boat with the bed packed with gear including 30 gallons of extra gas i averaged 21 mpg. Truck preformed great, i was impressed.
Last July, I towed my camper, similar to your camper from Omaha Ne to Loris SC. Travele speed 60 to 65, got overall 14 mpg there and back. Mine is 2021 LM2 engine. Doing the trip again soon.
That’s still pretty good mileage!
I love the 3.0 but I needed to tow in the range of 18,000 . I’m retired and soon will buy another toy box . I bought first a 2024 Chev 2500 Diesel Duramax LT Z71 . I love it . Don’t know yet mileage towing but I do know I won’t struggle with weight towing . I still Iove the 3.0 as well. Great design and technology
With that weight you’d absolutely need to get a 2500. I think you chose a great truck though.
If you want to tow 18K I'd say you are looking at a 1 ton 3500, probably a dually.
Nice video! You were very thorough. Appreciate that.
You’re welcome and thank you!
I drive a 2021 Sierra AT4 with the 3.0 Duramax. We pull our Dune scooters with it. On longer drives I get about 26.5 mpg but the same trip towing, it drops to 18 mpg while towing about 4500 lbs. Plenty of power and torque too. We like he Duramax so much that we bought a 2023 Yukon with the new Duramax. It gets like 28.5 mpg on the freeway at 80+ as my wife has a very heavy foot.
I think it’s a great motor and that the Yukon with it is going to quickly be considered one of the best SUVs you can get.
My 2020 Trail Boss with the 6.2 gets 9-10mpg towing a 29 foot trailer with a 6300lb dry weight and loaded with all gear for trips with full propane tanks and an extra battery so it's probably closer to 7200lbs. When not towing I get 16-18mpg in the city and 18-20 on long freeway trips. Road Active suspension springs solved my problem with the 2.5 inches of squat and took away about 2 inches of it so the truck rides level when towing. Great video illustration of the MPG's from the baby Duramax.
Nice video, i went from a 1 ton dually to the 1500 and towing is different. Towed 1700 miles round trip last week lots of hills and rain ended the trip with 13.1 mpg average. Very impressed with this little 3.0 duramax.
How much did your trailer weigh?
@@adamcrouch 7800 lbs.
Why in the hell would anyone purposely tow a travel trailer at 80+ mph? THIS is why I never loan out my trailer. smh
No one, and that’s the point 😉
are you not doing a video people can realate to? Weird attitude to have.@@MOHAWKAUTO
@@Joeyhurt1990 I think I’m making a video people can absolutely relate to. I wanted to tow the trailer as fast as I could safely, and I did. Did I expect to be able to actually tow it going 80? Not really, but I wanted to try if it was safe. I’ve driven 1 ton work trucks with much heavier trailers when I did drywall work a longtime ago and was able to go 80 without issue. Those were very different trailers that were properly balanced and level and the truck was level too. I never experienced trailer sway like I did during this video. So I think you might be speaking out of turn, which is a weird attitude to have.
Towing at 80, while doable is ridiculous. No reason to pull over 70. Things happen fast when towing and running 80 leaves you no room for error.
@@howebrad4601 I agree for the most part. Depending on what you’re hauling and what’s doing the hauling, terrain, weather, and where you’re driving, 80 is the speed limit and can be done safely as it’s flat, wide open multi lane interstate or highways. Plenty of space to have a big gap between you and the people in front of you. I just wouldn’t recommend it for most situations.
I have a 23’ GMC SLE 3.0 Maxtow package. 4x4 Crew cab with a 6’7” bed. So I have enhanced cooling. The 9.76” rear diff with 3.73 gears. At 18,000 mi my life time average is 24.2mpg. Thats with 2 winters of using remote starts. Unloaded averages 26-32 mpg. I pull a loaded down 22’ enclosed trailer. With a 5th gen Camaro. Around 9k lbs. Running at interstate speeds 70+. I have been averaging 12.4 mpg. Right at a 45% improvement over the 6.2. Also pulling up the larger hills in Kentucky. The LZ0 3.0 will not only maintain speed with power to spare. But can accelerate. The 6.2 on the same grade is pretty much on the floor struggling. And my 5.3 would lose MPH.
But the sound of the 6.2 is just music lol.
The 3.0 will walk away from a 6.2 if they are both loaded down heavy. Unloaded the 6.2 is way faster.
The 6.2 sounds so good! I’m happy with my 3.0, I just wish I could tune it to give it a little more pep.
@@MOHAWKAUTO just wait, it took them a minute to unlock the lm2, in no time the lz0 will be tuneable.
@@chrisguillen1495 I can’t wait!
14:10 exactly correct!! Thanks for touching on this!! People don’t understand that if you buy a truck built for offroad it isn’t going to tow like a truck with a “heavy duty towing” package, etc…thanks for that
You’re welcome! I want to make sure that those that may not know, understand the compromise. It’s not necessarily a bad thing, just something to be mindful of.
@@MOHAWKAUTO agreed, unfortunately I’ve seen it way too many times people going on their truck manufacturers website, finding a 2023 crew cab 4x4 short bed f-350 and assume OH, IT SAYS THIS TYPE CAN TOW 30k! When in all reality a Tremor package alone knocks this down severely. Payload, max tongue weight and even max trailer weigh are substantially different when these “packages” are added, meant for towing, offroad or otherwise. So many newbies don’t get this or think to look to begin with! Thanks again. I am subscribed to you now
@@ryanvegas777 you’re spot on and thank you so much for the sub!
Towing and offroad = 2500HD ZR2 Duramax
@@rsbreeze that’ll still have (should have) softer springs than the non ZR2 2500. The ZR2 2500 looks really nice too
I have a 22 Sierra SLT 1500 with the 3.0. I ordered it with the max tow package so it has minimal squat when hooked up to our trailer. Took it on a road trip last fall from north Idaho, through Montana, down through southern Idaho and back. Total trip was a little over 1,400 miles. Towed our Jayco 22RBS travel trailer. It's about 7,000 lbs. Total MPG for the whole trip was 16.8. The truck did awesome. I was very happy with it.
That’s impressive mileage!
I have a buddy who has one of these ZR2 3.0 diesel trucks and over a 2,000 mile highway drive at 85/90 mph he said that he was getting 28/29 mpg. I can’t argue but was blown away. My 2024 F350 SRW 6.7 HO Platnium Tremor gets 16.5-17.0 mpg driving pretty much how ever I want. I am looking forward to driving it real nice to see if I can get 20 mpg but I can’t seem to manage that 😂, it’s got 500HP and 1,200 ft pounds of torque! When I tow a 18k pound 42’ long, Brinkley Z3610 at 70-75 mph I am getting 8.9 mpg. So there’s that bit of information.
Thank you for sharing that! I’m always interested in seeing how the 3/4 and 1 ton options do during normal driving and towing
I have the 2023 Silverado 1500 RST 4X4 Diesel... Towed about 5000 lbs. from NC to South Florida my Sea Hunt CC boat and I was getting 10 - 11 mpg and it drank DEF fluid worse than an alcoholic... Normally DEF fluid lasts and still does a few FULL fill ups so no biggie... Go for a 12 hour tow and plan to bring a few 2.5 gallon DEF boxes in your truck bed... Sucks DEF fluid BIG TIME while towing that type of distance... At least mine did... Please NOTE: This truck set up NOT IN TOW drives like a Caddie on the HWY and pulls like a Champ... The torque makes other vehicles wonder what's under that hood when you leave them in the dust... Keeper for me... Thank you for this video... !!!
I used to have the exact same camper...towed from south texas to pidgeon forge tenessee and back. Avaeraged 13.4 mpg. Thought that was great! I have a wdh and it tows safe and level.
I have a 2023 GMC 1500 slt with the 3.0. I’ve towed my vehicle and it did great. I was ranging from 14 mpg uphill and then 20 mpg regular roads.
It’s a great truck and combo. I’d just plan on doing a trans cooler.
I have a 2023 AT4 LZ0 and am extremely happy with towing performance. After decades of hauling heavy loads, I can say that the wind resistance is a much bigger factor than the weight. The camper you pulled is indeed a brick. I can also say from much experience that a strong crosswind actually hurts mileage more than a direct headwind. Lots of guys will argue this point, but it's a fact. Aerodynamics matter more than most people realize. I've pulled up to 10,000 with my LZ0 and love it. Empty mileage is awesome! For anything bigger than 10K, I use my F350 6.7L Powerstroke, but for the light loads, I love the 3.0 LZ0.
I agree that a side wind has more effect and the math proves it out by calculating the area of the trailer side vs the front.
Cool video. I have a 6.2L Trail boss and pull that same trailer. With my 2 inch level the squat is loyal lol pulls nicely tho
Thank you, and that’s great to hear how someone else does with the same trailer
Last spring I purchased a 2024 silverado rst with the 3.0 and got 30mpg for an average in 500miles, hooked it up to my 7300lbs camper with weight distribution hitch and was getting warning lights and messages on the main display saying I was over loaded. Because i tow my travel trailer frequently I ended up returning the vehicle back to the dealer
I’ve never once gotten a message saying I was overloaded. I’d be surprised if I did too as it says 8700 on the sticker. For our next tow test, I’ll load it up more and see what happens.
I got a 2023 Silverado 3.0 not for the MPG but just because I like how the diesel drives more than the gas.
I love the way it drives and how it seems smoother and more effortless especially when going up hills.
My LZO Chevy tows like a dream at 65MPH...MAX!! Distributing hitch keeps it level which is a must...love my truck! Way better than my ECO diesel RAM!
Distribution hitches make an enormous difference.
Spent 4 yrs stationed at Mt. Home AFB! Loved Boise and Idaho in general!
It’s a great area!
@@MOHAWKAUTOno no no. It’s a terrible area and doesn’t even exist on any map.
@@AnontheGOAT sure it is! It’s right below Minnesota and right above Missouri.
My friend and I have exact same trucks other than I have the 3.0L and he has the 6.2L. Pulling almost identical campers (29'), i get just shy of 14 mpg and he gets just shy of 9 mpg. I really like my 3.0. It is very quiet under load and lots of power on acceleration. Also, I do not tow a lot and I drive about 12,000 miles per year. Last year my cost per mile was $0.167.
That’s awesome to hear! I really enjoy how quiet my engine is under load and the overall power and acceleration has been great for me. I’m looking forward to the summer months to see how much better the fuel economy gets.
Had a 2012 LTZ with the 5.3 and towed our 32' TT that will go about 7,000-7,200 lb. Over all on a number of long trips averaged right at 9.0 mpg. Now have a 2023 LTZ Z71 with the 3.0. Only taken one trip so far with the same TT. Averaged 13-14mpg on a trip of about 1,500 miles.
On the highway get between 25-28. Could probably bump that up some if I could get the CC to set around 65, but for some reason it usually is locked in around 78-79 because I have passed HP at that speed and they never even look twice and 65 on Texas interstates can get you run over.
Same issue here with fuel economy vs the interstate speeds. Really impressed with towing mpgs though!
I have a 2022 z71 rst crew cab towing the engine has plenty of power however I am debating about beefing up the rear leaf springs truck squats more than I'd like when towing 4 place enclosed snowmobile trailer but on the other hand pretty smooth ride on bumpy dirt roads 30mpg not towing 12.5 to 13.5 mpg towing depending on terrain
Had a 15 high country 6.2 that got 10 mpg towing my 5800 lb camper. My lm2 3.0 gets 16.5 and didn't drop lifters and beat the lobes off the cam so I'm saying the 3.0 is superior towing .
I think we’ll see the 3.0 become a legendary motor
Coming from a 3/4 ton truck , i am getting use to the squat on the 1/2 ton ZR2 , i tow a 7x16 double axle enclosed trailer with the 6.2 , definitely likes the fuel when towing but not as much as the 2022 hemi dodge i drove for a couple months .
That’s good to know! I debated getting the Ram 1500 with the Hemi and e-torque.
Easy to fix with air bags
@@100pyatt
Save the $$$ and hassle and use a weight distribution device.
I'm actually impressed! Seems solid. That squat 😂
this trim isn't geared for towing. it compromises towards off-roading, not towing.
That squat was crazy, but it handled well all same.
You’re correct and I thought I made sure to mention that in the video. Despite being built for off-roading, it’s still a truck and can tow as well as you’d like a half ton truck to be able to do. Although, I’d recommend air bags or something similar to help with stability and confidence.
The ZR2 has springs like a marshmallow lol. Intended to soak up big hits smoothly. You like to see squad look at Ford equipped off-road trucks.
@@slickcasner4205 you’re absolutely right and I knew it would squat because of what it’s designed for. It honestly could be a lot worse.
Very nice video. My experience with LZ0 AT4 towing 7400 lb extra height enclosed is 11-12 mpg over the mountains of eastern Tenn. Avg. 26 City every day. Love it.
That’s great city economy and not bad towing over those mountains!
I find that I typically get better mileage in Fuelly than what my ‘24 AT4 shows. I haven’t towed yet though, and only have about 1,800 miles on the engine.
I think that the difference in your trailering app vs the dash is the fact that you reset the dash trip when you filled up, and the trailering app was calculating from when you hooked it up.
If you’re going to tow regularly, the PPE intercooler and transmission base cooler would be really good upgrades to make.
I agree and I think no mater what I’ll do the PPE transmission cooler bypass valve
Nice info, I have a 2013 f350 super duty 6.8 power stroke. I towed a 11000lb heartland fuel 250 from Buffalo NY to Nashville Tennessee. I got 9.8 miles per gallon.
Have over 52,000 on my 21 and mileage has stayed pretty consistent at 13.8-14.7 towing and 25.8 city, 29-31 highway. Love mine!
I went from a 2019 6.2 to a 23 3.0 LZ0 and tow the same camper regularly (about 7,000lbs loaded). Highly recommend a weight distribution hitch and Road Active Suspension if you want to go 70-75mph. I average about 11.3mpg with a mix of driving from 60-75mph.
How does the 3.0 compare to the 6.2 for you?
@@MOHAWKAUTO no comparison absolutely love the 3.0 and would never go back. Fuel economy and towing being the main reasons. I’ve had the same tires and 3” lift on both rigs with BFG KO2 285/65/r20 and averaged:
6.2 normal driving about 15-16mpg
6.2 towing same camper about 7-8mpg
3.0 normal driving 21-22mpg
3.0 towing 10.5-11.5mpg
@@chrisregister510 that’s awesome! I know some people are saying that they feel like the 3.0 is gutless compared to the 6.2. Do you feel like that’s the case?
I have a 2022 Chevy 1500 RST Z71 with LM2 similar weight trailer. Trip to see the eclipse about 350 miles across north west Ohio some hills but mostly flat for 15.1 MPG. Going Michigan to South Carolina this summer so will have a wider range of driving conditions, see what that gives us.
I think this is a good match up of trailer and truck. Last year had a 2021 Chevy 1500 LT with 5.3l gas and same trailer for about 9 MPG on Michigan to St Louis trip.
I had an lm2 2 years ago. Crew cab slt 4x4 with 6.5 ft bed.Towed a dump trailer on occasion and it did not like it. Between the load and trailer it only weighed 7500 or so with my capacity at 9300. It struggled on a flat road to get to 45mph. The site was only 2.5 miles from my house and the small hills made it struggle even more. The pedal was in fact to the metal and was only able to go 25 mph. It was in tow haul mode. After that 25k the high pressure fuel pump blew. Not sure if it was connected to towing the dump trailer but was very strange. Now I’m back in an lz0 gmc elevation with max tow package.
That’s crazy about how the LM2 was for you. How does the LZ0 compare to you?
Pretty much what I expected. Have a 2016 Colorado 2.8 and tow a 29' toy hauler at 6000 lbs. and get 12-14 mpg at 65. Get 30-32 mpg with no trailer at 65.
That’s impressive!
I get about 32 with my 3.0 running 70 with the cruise set.
I have 3.0 2021 GMC AT4. I tow my 7400lb boat from TX to CA. 12 to 14 mpg was my average. Truck towed great I didn't even feel if the was a boat in back of my truck. I did used alot of DEF. It was in tow mode and I was told not to use the tow Mode. Tow mode uses more DEF. Don't know if thats true but I'll tow without the tow mode next time and see if there a difference.
I have a 24 Sierra with the LZ0 with a 6” lift on 35x12.5r22 mud terrains and on my recent trip towing a 7200-7500lbs trailer 180 miles trip I got 13.9 mpg. Compare that to my 20 Denali with similar lift and tires with the 6.2 I got 6.6-6.8 mpg on the same trip.
I got 2023 escalade with LM2 with grand design 30 ft trailer. With fully loaded and 4 adult and 2 kids. Towed camper to Joplin mo from Indiana and back. Average speed 70 to 85. Both vehicles fueled up and passenger on board grossed at 14480 on CAT scale.😂 cruise at 75 and up to 85 when passing average 12.38 to MO and 12.22 on the way back. Calculation was done on the apps. It's pretty impressive.
That’s very impressive and I’ve been curious how the 3.0 performs in the SUVs. Thank you for sharing!
100% you are over payload. Plus pulling that much weight at 85mph is very dangerous.
@@fit4ya1975 not sure he asked for your input.
@@ericschroeder784 Not sure either. But I know for sure I didn't ask for yours.
😂
You can get towing package on any trim i believe and it gives you added springs in the rear among a few other things. Doesn’t come stock
I think if you’re going to tow everyday a heavy duty is the way to go. I have a 22 f250 and was going back and forth about getting the 3.0 duramax but was nervous I was going to get significant mpg drop when I was towing. For reference I avg about 18 mpg with empty and about 15-16 well towing in the city with traffic on the highway and streets.
I’d be inclined to agree unless it was a small/light trailer. I’d personally get a heavy duty if I towed everyday
Pulled a similar trailer with my '18 w/5.3L and averaged 10.5 mpg over 1500 miles (including climb the grapevine in CA.)
Squat in my opinion doesn’t mean very much. What’s going on is the leverage and force being applied behind the rear axle which is taking weight off the front axles making your set-up dangerous. Unfortunately airbag manufacturers market airbags like they actually do some something. A load distribution hitch will actually transfer the weight as it should be for much safer towing.
I agree with your thoughts and airbags wouldn’t be my first choice.
I am very impressed with the 3.0 and how good the milage is with a full sized truck compared to gas.
I have the Colorado 2.8 diesel and I tow a 24 foot duel axle travel trailer toy hauler at between 5000 to 6000 lbs depending if I take my Victory Vision with me and if I fill the water tank ect. I get 14-16 mpg. The tongue wt is 700 lbs and I use weight distribution hitch and I do get blown around a lot. But I am extremely impressed with the mileage while towing a square box at speed. My Colorado gets 30-32 mpg unloaded.
Those are great numbers!
Just for comparison, I have a 2019 5.3 with the tow package. I pulled my jeep on a trailer (about 6000 LBS) too Utah and back, round trip was about 2200 miles. I averaged about ten miles per gallon, and It did tow with easy. I would rather have the 6.0 or the 3.0 diesel, but this is what I could afford at the time.
That’s good information! Thank you!
So as a guy with a lower hp titan cummins, i agree with what you are saying. You bought a truck that suits you and your needs, not someone elses. I tow oftem with my truck, and also live in boise. My trailer is closer to 10lbs but my numbers are not far off of yours. 9-12 towing depending on speed and weather. No load 18-21.2 also depends on speed. Best i have gotten was no load, 55mph run at 23.4, from blacks creek exit to cloverdale and no traffic. People discount the small diesels, but only because they think they will tow a house all the time, 90 percent dont and use their diesel truck as a commuter.
I agree that so many people buy more truck than they need, which is fine. I just didn’t want to spend more to buy a truck and then spend more for fuel because of worse mpg. It’s far more cost effective to buy a distribution hitch and airbags (or something similar) to tow safer than it is to get a HD truck. The small diesel half tons are great options.
Excellent points! I know I love my 2022 3.0 Duramax and I don't see myself ever going back to a gas powered truck.
@@edwardpate6128 after owning this, I’m not sure I would either
I got a 23 at4 with the LZ0. Towing my 7x23 inline enclosed trailer and I get anywhere from 11.5-15 mpg depending on time of year. Winter diesel is worse mpg vs summer diesel. Empty I get about 22-28 mpg on highway going 75-80 mph and I’ve gotten as good 34 mpg going 60-65 mph. Never gotten below 11.5 mpg towing.
That’s impressive!
Nice video! Question? What fuel app do you use?
Thank you! I use Fuelly.
@@MOHAWKAUTO Thank you!
I found in that state the only time the wind doesn't blow you away is when it's super hot.
Nice bro! I know those roads. Hey need to do one on Middlefork and see the mileage.
What do route do you think I should do?
@@MOHAWKAUTO To Atlanta via Arrowrock. I have a 3/4 ton Duramax and tow up there all the time. Have been very curious how one of the 3.0’s would do! Love the idea of doing with a 3.0 but not sure how it would handle the grades. Great video by the way. I get the wind there, in-laws live out in Hagerman.
Rather than MPG.. maybe do a Cost Per Mile... Considering Gas (87/85 Oct) Cost vs Diesel/DEF Cost. what's the difference in cost per mile, because MPG doesn't consider DEF usage and difference in fuel prices.
You’re right, but I wasn’t comparing this to gasoline. DEF usage varies greatly based on a ton of factors so that’s hard to calculate anyhow. I also consider DEF to be inexpensive enough ($15 for a 2.5 gallon box) that I don’t factor it in. I have almost 7k miles on my truck and I’ve only bought 2 boxes. $30/7000 is 0.004 cents per mile. If I towed a lot more, that would change and it would be something more to consider. I usually look at the percentage cost difference between fuel vs percentage difference between mpg. The cost per mile method is a great way to look at it also.
I have a duramax Zr2.
I average 25 mpg. I previously had a ram hemi it averaged 15.
Even after the increased fuel cost I’m still saving like 1,200 a year running my average 12,000 miles.
Just food for thought…the closest comparison on gassers from GM is the 6.2 (also mentioned in this video), but lots don’t realize the 6.2 recommends 91 or higher octane…the price per gallon ( here in vegas, today ) diesel is around $4.10/gal and the cost of premium is around $4.35/gal…now add in the worse gas mileage and there is no doubt how a video like what’s suggested would turn out…
@@johnmorris77 thank you for sharing!
Diesel is cheap if you run offroad fuel.

I’m itching to pull the trigger on a new ‘24 High Country w/Duramax. What’s the scoop on adaptive ride control? I don’t tow (yet) but am anticipating getting a travel trailer.
If you’re taking about the adaptive cruise control, it’s an amazing long trip aid. It takes cruise control to the next level by matching your speed to slower vehicles in front of you (when needed) and keeps a consistent distance based on your preference. If you or they change lanes (and assuming no other traffic is impending you) the truck will resume whatever speed you set.
I’m not. It’s adaptive ride control. Never have had it in a vehicle but I drove a 24 with it and the ride was super smooth. Similar (not quite on par) with ride from a Ram 1500 Ltd with air ride. ARC requires 22” wheel package + $900 for suspension. So, total is roughly $3300. I’ve heard replacement shocks are like $450 a pop though… :-/
@@chrisbrewer3886 I misunderstood, sorry about that. It’s offered on the High Country and Denali trims only which haven’t interested me much so I never looked into it until now. It sounds like an awesome setup from what I’ve just researched. I’m just too unfamiliar with it to make an assessment.
This time of year with Winterized diesel at the pumps will drop mileage quite a bit. I know from experience with my 2022 LM2 and my old 2001 Ram Cummins thats the case. Also, what does your cargo/towing sticker in the driver door jam show? My GMC shows 8,800 lb trailer with 880 lb tongue weight.
I’m looking forward to winterized diesel going away as that’s all this truck has run on so far.
I will say that I have no issues getting 32+ mph going 70 with the cruise control obviously not towing here in Michigan on flat ground and 25 or more in mixed city and highway during the warm weather months. Just filled up last week and in mixed driving I had 22.5 over just under 600 miles. @@MOHAWKAUTO
@@edwardpate6128 that’s good to know the difference between the diesel offered in warm and cold weather!
I towed a fifth wheel camper out west and through the mountains and averaged 13-14 mpg with the 3.0. This really isn’t a good comparison because no one should pull campers at 80 MPH. You’ll get a few MPGs if you stick it around 67 or so. Also installed airbags because the stock suspension is way too soft for any significant towing applications.
I never towed at 80. I had the cruise control set to 62 because of the higher wind conditions
I have a ‘21 LM2 RST and I tow a 38’/10k lb Travel Trailer. I get 13.5-14.5 MPGs Towing and I tow often because my wife and I are Full Time RVers.
I’m old. I grew up on a cattle ranch and we also cut tens of thousands of cords of wood.
Today’s 1/2 ton pickup’s especially the Chevy and ford pickups can be configured in a manner that makes them better than any 1-ton SEW pickup made prior to 2005.
My Dad, in 2010 bought his last pickup to pull a 35’ fifth wheel he and min would pull all over the US. He had a 1-ton srw 2000 Ford and replaced it with a 2010 F-150 king ranch. It had the 6.5’ bed and the max trailer package. He replaced the tires with Michelins LTX M&S load range E, added rear tow air bags, a performance exhaust. That 1/2 ton had the 5.4 3v and a 6 speed transmission. We drove from San Bernardino CA all the way to Lake Tahoe mid summer. I drove 2002 F-350 with a diesel and a 32’m fifth wheel. Dad drove his 1/2 ton with his 35’ trailer. On the way up to Tahoe he was able to go up the steep inclines better than my truck and trader up!!!!
Here is the deal. Take any crew cab long bed 1/2 ton today. It will: (1) weigh more than any 1-ton SRW crew cab made before 2000. (2) have better stronger brakes (3) more power and torque (4) stronger frame (5) better sway control and safety features (6) stronger frame, stronger body and much more stable.
The point is, any modern properly configured 1/2 ton today with a good set of rear airbags is light years ahead of the HD pickups for towing really until the last three generations of HD pickups.
Where the older pickups had an advantage over todays 1/2 ton is the HD trucks had stronger axles, springs, differential housings, bearings at load points and the old diesels (pre the EPA destroyed them with excessive emissions standards) etc.
I’m not trying to advocate people go out and tow 18,000 lbs with a 1/2 ton and some air bags in the rear. Yes it can be done safely and yes it would be better in many aspects than buying a like new 1999 f-350. I’m just saying if we are truthful about the realities of how much better today’s light pickups are, they are far more capable than their manufacturers set limitations.
Here is why I always tell young folks to consider when getting into a new rig. We live in a different nation than when I was your age in the 1970’s and 80’s. Back then police, except for NY or democrat controlled states would leave people alone for the most part when towing. I can genuinely say that 100% of the farmers, ranchers and construction companies of that time regularly towed or carried much much more that the pickups were certified to carry. For example, 68 we purchased a new single cab F-250. We installed 5’ high side boards with two 30 gallon propane tanks built in about 1/2 way up. We regularly loaded that pickup up with one cord of green firewood which weighed about 4300 lbs. Then we would attach a 4 horse tongue trailer with another 5 cords of green firewood and I would drive it to school in the morning (we lived near Piñon NM and I attended school 78 miles away at Artesian High School). After school, I’d drive it to a customer who would buy 200 - 300 cords of wood every year to resale. That 6 cords of wood, propane, full tank of gas, 4 horse trailer, two spare tires and a heavy duty jack (we blew tires all the time with the heavy loads) probably weighed around 17000-20000 lbs.
I saw farmers pulling modified semi truck trailers with 300-400 90lbs bails of hay. Did accidents happen? Yes, rarely. Thank God we never had one. But the difference from now and then is: accident trial lawyers have turned accidents into lottery winnings. Hell, hot coffee spilt in a lap netted millions of dollars in lawsuit awards. Today juries are idiots. They’ll award 500 million or a billion dollars to individuals who called victims today where in 1970, they’d be called idiots and “get what they deserve”.
So because we are a litigious society with piranha lawyers, professional gang organizations that seek out over loaded pickups in order to force an accident in order to sue…. Well if you in an overloaded pickup, even if it’s only a few hundred pounds… you’ll be ticketed and even if you didn’t cause the accident, you’ll be sued and most likely lose.
So buy a truck and trailer that will keep you well inside the safety parameters.
You have a lot of great points. I’d like to get air bags or something similar so that I can tow anything I’d like with concern that the squat is going to make it less safe. As you mentioned, mechanically it can handle the weight fine, it’s the suspension that makes it a problem. I recommend stepping up to a 3/4 or higher for those looking to tow a lot regularly more to protect their warranty than anything else. I’m not concerned about being sued for what or how I’m towing, I’m concerned that I’ll have something that needs to get fixed under warranty and it will be denied because I overloaded. I have insurance to protect me from lawyers (I’ve been in insurance producer and am still licensed so I know how to protect myself), but I don’t have the same level of protection for when the manufacturer wants to deny warranty claims. I know how to fight those too, but not everyone is as willing or able to fight when needed and it may be easier and cheaper to pay a little more for a heavy duty truck than have to deal with paying for parts and labor for something that should have been covered.
Funny I get 6 mpg to 8 mpg with my 6.2 going through the mountains of Wyoming. Same amount of squat though. But I’m towing grand design transcend 265bh which i think is t”little longer than the one you were towing. Just one caveat, mine is the supercharged 6.2 hellcat TRX.
That’s a whole other animal! I reviewed a 2024 Final Edition TRX just a few weeks ago and that truck is awesome!
I have a 2022, High Country, 4x4, LM2 3.0 Duramax towing a Grand Design 2500RL (about 6,750lbs). I get about 12.5 at 65mph through the midlands to the coastal areas of North Carolina. Not towing I get from 24 to 27 mpg at 75 to 80mph.
That’s still good mpg, especially for a half ton
My 2023 Z71 RST gets awesome gas mileage. Towing my cattle trailer with 3000 lbs of cattle, I have averaged 13 to 15 miles per gallon. Wind definitely plays a factor.
That’s great mileage for sure! Does your RST have the 3.0 also?
A question to which I suspect I am correct on but wanted to make sure as per the ZR2, your truck has the fast gearing as per the 3.23 ratio correct ?. My understanding is that GM has not made the 3.73 ratio optional in this truck which with the larger tires and the expectation of a more off road oriented truck, is completely ass backwards to anything logical.
You’re correct that it has 3.23 gearing as I don’t believe you can get max trailering package on the ZR2. It looks like the 6.2 has 3.42 gears though based Chevys media page.
@@MOHAWKAUTOYes, that all computes with my findings. But as I pointed out the ZR2 is in a different category somewhat like a Jeep Rubicon for example and it comes standard with 4.10 but can be had with 4.56 or 4.88 gearing and yes all because its designed even more so for off road vs a regular Jeep Wrangler. I just don't understand what GM is doing and neither would the off road community.
I have the LM2, towing my 7k lb camper I average 12mpg. The winds play a HUGE factor in fuel economy; so much that sometimes I pull up behind tractor trailers to catch the draft, which always saves me about 3-6mpg. No joke
my 22 trailboss with the lm2 towing my viper (roughly 5k lbs total ) on an open trailer gets almost 20mpg if I keep it 60-65mph and than at 75 I get around 15.5-16 mpg
That’s really impressive!
Towing 6,800 TT gets about 14-16 in normal conditions. I go 65-70 mph though. The best one ever was with a 30 mph tail wind I cleared 20 mpg! But that's an outlier and shouldn't really count.
Overall great engine, you made a great choice or that weight range of TT. Anything over 10k wet, I'd go HD.
I’d agree with going HD. There are some half tons that can tow 13k, but I’d be more likely to upgrade to HD if I was towing 10k often.
Just towed 9000# 300 mile round trip. With new 24 trail boss 3.0, Just did the limit Did not push it. Got 16 MPG, bucking a strong wind for 1/2 that trip. Did the same run 2 days later not towing , also bucking head wind for 1/2 that trip ,got 26 MPG. Got 1000 miles on and topped off def , took 2 gallons Def tank holds 5.4 gal. Should go 2000 miles and not run out. It has to use Def and if it sucks more than you might like it's only about a penny per mile. I'm ok with that
Just imagine how much better mpg would be with a leveled ride and weight
Exactly
Great Presentation! I have noticed that in several RUclips videos, many have commented on the DEF and also, the unexpected high usage of diesel oil, and it appears that the diesel oil is headed towards the turbo. In the video, it mentions that PPE has developed a Prototype Catch Can for this oil problem and is being tested on vehicles. Please provide a comment in future 3.0 LZ0 Duramax ZR2 video, whether your Dealership and your mechanic can provide any feedback on if the current 3.0 LZ0 Duramax oil leakage problem is a problem and will be address by GM / Chevrolet. Best, Steve from Western Mass.
I have heard of some vehicles experiencing these issues. While I’m interested in the catch can PPE is developing, it’s purely to reduce oil and other crankcase vapors that don’t belong in the intake, out of it. This is something common on many engines. I haven’t had issues with what I consider to be unexpected DEF consumption, although I know that it uses a lot while towing and that’s what other RUclipsrs have been doing more of compared to me.
You should’ve done a third test, towing the trailer in standard mode instead of the tow/haul mode
Given how low it sat in the rpm range and how it wasn’t shifting a lot or hunting for the right gear, I’m not sure it would have made too much of a difference. I am thinking of doing another tow test and if I do, I may consider this as you’re not the only person that’s suggested it.
I have a 23 z71 with the baby-max and i use DEF almost every 1000 miles, but it’s hooked to my work box trailer 95% of its life. AVG mileage is 15 MPG with a heavy load.
My 2020 6.2 1500 Sierra is terrible pulling 9000lb 28ft travel trailer!! Avg about 5-6 mpgs going about 65-70 mph over 180 miles on flat freeway!
That’s crazy!
So my high country with a 6.2 got 9 mpg with a bigger trailer 6800 dry 34 feet long 850 toung on a 70 mile drive. Went from 3200feet to 3800 feet with 3 big hills.
I’m sure the high country version with the 3.0 diesel would get better economy than what I was getting.
I plan on getting a zr2 bison probably going to wait when the 2025 comes out. Debating if I should get 1500 or 2500 though, I got a boat it’s little over 5,300 lbs. I plan on getting a rzr as well. Just stuck on which to get
I like the 2500, but the 1500 is capable of towing what I need and the day to day fuel economy was more important to me
@@MOHAWKAUTO yeah both look great I’m leaning towards 2500, I’m probably going to test drive both and see how they feel out
Lol, I get 10.7 mph just driving to work on normal roads in my 6.6 duramax. The fuel economy onnthe 3.0 is great! 😅
That’s crazy! I do hope someone develops a way to tune and mod the truck to get more power out of the 3.0. I’m sure there’s a lot of untapped potential.
Hard to argue with a guy who uses testing methodology similar to TFL and got his Jayco from Josh the RV Nerd"s employer (Bish's RV). 😆 But seriously, nice test. Well done
How much oil does it use between oil changes,i don't care how much it can tow if its going to drink oil.
As far as I can tell, very little if any. I haven't noticed any drop and I'm getting ready to do the second oil change already with almost 8500 miles.
@@MOHAWKAUTO well maybe they addressed that issue, or maybe you got a good one
@@BM-cz1xb both are possible. There was a lot of changes and improvements made with the LZ0 from the previous LM2.
@@BM-cz1xb The LM2 used oil and the source of the oil consumption was identified by GM. The valve cover is plastic and has internal chambers to separate oil from gases leaving the crankcase. An internal weld was defective and allowing engine oil to get pulled out through a ventilation tube. There has been a TSB out along with a new valve cover that fixes that issue. There are quite a few youtube videos that mention oil consumption with their truck that are totally unaware of the TSB.
Boise also, Towing with 7.3 Godzilla, 7.5mpg towing 8000lbs. When the wind is blowing in Boise its because it Sucks in Mt Home.
🤣
Pulling the same jeep and trailer (8550 lbs), My 2020 3.0 gets 18% better fuel mileage than the 2012 6.6 Duramax and 2017 Nissan Titan Xd 5.0 Cummis I had. And when I am not towing the 3.0 gets 47% better fuel mileage than the other tow trucks did. I do run a weight distribution hitch to make the 3.0 truck ride level when towing the jeep and trailer.
That’s an awesome boost in fuel economy. I plan to use a distribution hitch for towing heavier loads.
How did the Titan XD handle the load while pulling? Not power wise, but stability?
@@exordis It handled every bit as good as the 2500 6.6 Duramax trucks.
@@lt99ls1 Good to hear. I love the idea of the 3.0, but also love the idea of the heavy half ton. Especially if the ride isn't too compromised (with the gas 5.6).
Love that rig, but a 2500 diesel gives you more stability. I'll sacrifice a bit of mileage for the safety factor when towing.
I see your point. However, this trailer isn’t nearly heavy enough to be a safety concern. Using the weight distribution hitch would have resolved the stability issues and that’s considerably cheaper than going to a 2500.
What app are you using to track your fuel?
Fuelly
suggest flipping that hitch around if possible to get the trailer level
That’s a good idea. I’d like to do more testing on leveling it. I know that the water tanks are located at the back end of the trailer which would act as a counter weight to the front. So it’s possible it could have been a bit more level just by filling them and not having them empty. I have a little pop up at the moment that I’m not worried about towing at all since it’s so light. However, we’d like to get a different trailer at some point.
2022 GMC Sierra 1500 SLT with 3.0 diesel. I tow 7000# 1200 to 1800 mile trips and average 11 mpg at 72 mph.
i have 23 denali 3.0 and the difference is on MPG... you reset your trip at the pump and the trailer MPG does not reset like that so leaving where you got the trailer hooked up and created that profile is part of the trailer MPG so that is why they have different numbers
Love my gladiator Rubicon getting 30+ MPG with my eco-diesel.
I looked at the Gladiator, but there isn’t enough room for the family plus dogs and the towing capacity wasn’t as much as I’d like.
To improve the sag, driving performance, and safety I would add four Bilstein 5100 struts and a RAS -Road Active Suspension kit for the rear. Regarding the MPG, this diesel motor will really improve fuel goats for driving distances while carrying dirt bikes, passengers, and gear.
I got the diesel because the 5.3 and 6.2 have had a lot of problems
Reliability is one of the reasons I got the diesel also
I see roughly samething 12, sometimes 11mpg with a snowmobile trailer at 2800-3k lb its the boxy size that kills the mpg. My buddy has a 6.2 GMC and his truck gets 9-10mpg while towing same trailer. Specially at speeds 70 and higher.
I have a 23 with the LZO engine, max tow package and regular tires. I tow a Lance 1475S -small camper. Over 10,000 miles we are averaging 17.2 mpg. I try to not go faster than 65. I have the transparent trailer feature and is fantastic. John
Be sure to get a lock for that hitch. Easily steal-able ...
Locks are very important for sure
I'm pretty sure that Chevy says that truck is not rated to tow that much weight without a weight distribution hitch. I was looking at the 2024 GMC Sierra 1500 AT4X diesel, which is pretty much the same truck, and the Trailering guide for that vehicle says the maximum weight of the trailer without a weight distribution hitch is 5000 lbs and max tongue weight is 500 lbs. If you use a WDH properly, the max trailer weight goes up to 8700 lbs and the tongue weight to 870 lbs. Because you did not use a WDH, I believe you just made a video for a situation that no one should ever do, which is towing beyond the rated parameters of the vehicle.
Also, airbags will not help much with squat. That what the WDH hitch is for. Airbags are primarily for load carrying capacity inside the bed of the truck, not tongue weight. They do, however, help with lateral stability while towing.
I tow a similar trailer, 34 foot freedom express. I put sumosprings and supersprings on my truck to eliminate the squat. I usually get 16-18 towing, depending on terrain. Through Shenandoah park, definitely got less. Up to Maine, got way better. Definitely drinks def towing though. Not towing, dude 27-28 mpg all day.
What are you driving?
Silvey 1500 with the 3.0. LT.
I’m not sure about towing a trailer at 80 MPH when most trailer tires have a speed rating stamped on the side of them that’s usually between 62-67 mph. I have seen them go to 80 mph but they are hard to find. My max speed when towing a camper/ toy hauler/RV would be 65, maybe 70 mph max if only just because the wind. Nice vid but stay safe.
Thank you!
I’m going to look at an RST tomorrow with a max tow package 3.73 gears 3.0 D max. It was hard to find. I’m moving down from a ram 2500 with the 6.4
I am curious to know if that truck will have the two speed transfer case ( another words both high and low range four wheel drive ) as my guess is it won't if its a new truck, also assuming it is a 4x4 pickup that you are looking to purchase. Perhaps there are oddities out there but from what I have seen only the high country/denali in a 1/2 ton can have both the max tow package AND the two speed transfer case. ( gas being a 3.42 ratio, the diesel 3.73 like the RST you will look at as per the max tow ratios ). It boggles my mind why they are doing this and its easy to slip up in buying a truck and "assuming" of course it will have 4 low and then realize after that it does not. It may not be a deal breaker for everyone but I know for me its absolutely a deal breaker not to have four low in a 4x4 pickup.
@@charlesb4267 the window sticker says auto trac transfer case but I’ll definitely look at that
@@sevaguillon1619The auto trac aspect persay is about the ability for it to be in the 4 high auto mode so that the front axle will engage if it senses wheel slip on the rear axle. That auto trac system is available in both the single speed transfer case and the two speed transfer case. The controls for the transfer case for the auto trac system with the 4 low will have four buttons. 2 with an arrow pointing up, Auto, 4 with an arrow pointing up, 4 with an arrow pointing down. Now the single speed transfer case will have three buttons, 2 with arrow pointing up, Auto ( its a wider button covering the space of two buttons ) and then 4 with an arrow pointing up. Like I said, its extremely easy to gloss over that as the vehicles are new and its so easy to miss something one thought the truck would have and then realize it does not. If it has the two speed it should say on the window sticker " Autotrac 2-spd transfer case ". How I know some of his was because a heavy duty mechanic friend had just bought a 1500 high country a few weeks ago and the reason he bought that one in the lot was to get a long box ... 6.6 foot that is, and the towing package with the 3.42 ratio and 7300 GVWR and in his case the 6.2. He never even realized anything about this transfer case issue until after he bought it and I pointed out to him YES yours has the two speed !. He was in a rush to buy it as his prior truck got smashed into by someone that went flying through a red light and so admitted he was going in a bit blind buying the new truck but that sales person is the fleet sales guy and has some brains unlike some sales people. After you have had a look at the truck and discussed what truck has the options you are seeking, do drop a line here as I am curious to know what you find out.
I think you’ll be surprised with how well it does and the RST is a great looking truck. My brother in law had a 2500 6.4 and it was a dog compared to the 5.7 in the 1500 because of the gearing. The 3.73 gear will help the off the line feeling and should help improve in town fuel economy.
So many people will never use 4 low in a pickup so it may not be a big deal. I know I’ll only use it in very rare instances myself, but I prefer to have the option and not have to worry.
Cool video and comparison.
It will be really neat to see future comparisons on PHEV like the Mitsubishi Outlander and Hyundai Sante Fe. They are SUV's 7 seaters. The neat thing about them is that they can operate in series where the gas engine acts as a generator to drive the electric motors. There is three different selectable modes on the Outlander. They are ranging between 51-100km on the battery then you can use engine to be generator or be an engine and mechanically drive. Cool things in PHEV coming. Check out Edison Motors for heavy duty use and models
Considering the fuel savings on a day to day basis; if you don't to frequently, the 1500 with a 3.0L and that load is going to cost less and still be fine as a daily driver empty.
I have a 21 LM2 with 110 000 km on it. The thing pulls better than any other half ton I have ever owned. My fuel mileage with the 25 ft sled trailer fully loaded was always around 14-15 L/100 with winter diesel. I have never max towed in the summer. The only concerning thing when towing heavy loads with these trucks is the DEF consumption. I can expect to have to put a jug (10 litres) in every 1600 km. I can have a quarter tank and put a full jug in and the 1600 km to empty DEF warning comes up almost immediately when it sits at 3/4 of a tank of DEF.
It does use a lot of DEF when towing and that is a drawback. However it makes up for that in every other way in my opinion. So I just monitor it more closely and roll with it.
I’ll stick with the 3.5 ecoboost from ford. 17 mpg average with 34” tires and tows like a beast. No def needed and cheaper fuel. Get 11 mpg towing 8000 lbs.
Thats not a bad choice, and I like the ecoboost engines
I’m gonna call BS on the 11mpg towing lol.
@@AnontheGOAT worst I’ve gotten is 9.5 climbing mountain passes in eastern Oregon all day or in the coast range. Hit any highway or interstate and 11 mpg is easy.
@@kensporalsky3784 maybe on I5 but definitely not on I84 through the blues.
@@AnontheGOAT so if your basing your comment and saying I can’t get that mileage on one section of highway from Pendleton to baker then you are right. Yay for you. Buy something else and get less towing and even less by a huge margin around town not towing. I’ll keep my tow beast that no other manufacturer comes close to. Unless you switch the conversation to diesel. I have one of those to and will still go with Ford but all the new ones of all brands suck
Boise to Stanley and back would be a good test.
My 2003 2wd duramax 2500 lb7 gets 16.1 mpg towing 9100lbs -911lbs on tongue
I have the 6.2l in a Ltz trim. I get 20 mpg on the hwy and I tow my travel trailer that’s around 7,000lbs and while towing I get 10.5mpg on flat to small elevation change hwy speeds. Not a huge difference from what you got. But the lift on the zr2 must really hurt your fuel economy because my buddy who has the 3.0l in RST trim gets 28 mpg on the hwy. seeing your test just make me think 6.2l is the way to go, as long as you tune out the AFM.
I just got back from a long trip and I was getting closer to 25 mpg. I’m confident I’m going to get much better economy when the winter fuel goes away, although I’m sure the lift and tires are hurting the economy compared to other trims. Also, that 20 mpg is the most impressive fuel economy I’ve ever heard a 6.2 truck get. Even still, if fuel economy is a concern, the diesel is still cheaper. Based on your friends 28, and your 20, diesel could be as much as 40% more expensive and you’d be even as far as how much you’d spend on fuel.
