Thanks for watching. Check out this GM vs Ford HD Diesel MPG Comparison: ruclips.net/video/JwBiUFMN8kQ/видео.html
its funny how they made a big deal about vw and ram trucks putting out 2 much pollution and fined them big time but they let this company make these trucks called gliders. its a new truck with a older rebuild diesel engine in it they don't have emissions controls on them because of the loophole. in the law. how fare is that. people look them up.
Look you guys are nice enough but you are not even using these trucks how they were designed in these scenarios. Your passing off your “stress tests” to people who probably don’t know any better. Also it was hard watching you two with the tow hooks Jesus it was sad.
@@bigbossman5969 because all the emissions on big trucks ruin the motors and cause a lot of downtime. And I think the older motors particles are bigger and fall to the ground where emissions trucks atomize it and put it into the air. Down time fixing emissions trucks cost truckers too much money and can ruin a business that’s why they buy Gliders.
I don’t have an issue with the hooks on my travel trailer. I have the 2016 Silverado. While it is awkward and a strange design, the hooks do work with it.
The Cummins I6 Diesel & The Duramax V8 Are Matched Up.
In the 2017 GMC HD vs Ram vs Ford test at11:09, Kent said about GM, "using the grade shift, the exhaust brake, and your cruise control if you use the cruise control, and it will just lock on. You don't even touch the brake." Since you don't use CC in your tests perhaps at least making this statement in the downhill analysis somewhere would keep viewers from mistakenly thinking that GM's exhaust brake doesn't work very well. Obviously, it does.
Wish you had a decently wide, steep, dirt, flat, straight mountain road you timed, measured, or raced heads up 1 on 1 with all those mountains yall have...we have some gravel pits up here in northern, MN ?? Lol frfr
Keep up the good work, Mr. Truck & TFL are the only ones to give actual info. mpg, towing, proper towing, capabilities.
Thanks
Will do
1st- I suggest you use the grade braking and exhaust brake as if you owned the truck. If the downhill braking is too strong, then step on the gas. Otherwise use cruise control. 2nd If you have to guess at the time, then a redo is in order. 3rd-Maybe the personal opinions should account for only 2 points not 25. From the comments we can see how much brand loyalty exists. So, a true test should be more fact driven and less subjective. Nathan is biased. Just like most of us. Sorry guys, love this test except for a few methods.
L5p is the top dog here.
Cummins is the ultimate towing engine!
I want a Cummins diesel with the Allison 6-speed that would be the shit
I would prefer the Aisen that comes in the 1 ton, 4500 & 5500 Rams. It does handle more torque and power than any other transmission on the market (this type truck). I agree the Chrysler transmissions in the 3/4 ton and some 1 tons of late are not very dependable.
Gonna have to take off points for the chains on trailer sucking and not hooking to the hitch that GMC did not make or design and we are going to give it a low rating because the exhaust brake actually works and we don't know how to use it correctly
i have a 2018 GMC Sierra HD with the L5P. I live in Denver. I tow my 15k lbs toy hauler over this pass all the time. I do not touch the brakes going down hill. I use the cruise control, no brakes needed. Lots of steep passes all over Colorado. I can't think of one pass, where i the exhaust break is not sufficient.
In my opinion, you guys are not properly 'driving' the truck.
Thank you for the videos and reviews. very appreciative of your efforts.
Watch a mechanic today chip out soot from a Ram 3500 diesel air intake at the heater grid. I had so much soot that it was about 1/4 inch thick and no way could air get by killing the power of the engine. This is typical l everyday stuff I see as the from all the soot and bad expensive EPA equipment on these trucks.
I think a lot of this comes from people starting their diesel, driving 2 miles to work, and then shutting it off. This is what a coworker I know has told me, and he knows a lot more than me about diesels.
It's disappointing that they need to use a weight distribution hitch on HD trucks. To me if your truck needs help you don't have enough truck.
good video as always
My new Duramax lost an injector at 8000 miles I wouldn’t advise buying one. I regret the purchase
You also have to take into consideration the overall quality of the truck. I owned a 2014 ram 2500 Cummins and in 4 years there has been over 8 recalls on the truck/engine. Plus the Allison trans will last way longer. For these reasons I made the switch to GM.
No one talks about how much these trucks cost to own: 1 more expensive fuel 2 more expensive tires 3 way more x5 expesive to repair. I have seen in my work $7,000 turbo replaced -13,000 injector replacements - short blocks replaced $14,500. If you don't need to tow over 12,000 pounds dont buy one unless you are rich with cash. I did not ever get started about how awful they drive in town and hard to park, no rack steering on these trucks old ball joints and heavy steering. Then DEF problems are off the scale expensive $9,000 def regenerator.If you think about these videos these guys are in the busienss of selling trucks not really talking about the good bad and ugly of owner ship.
so your telling me the guy rated the truck for it’s hook ups not its capabilities
Can I borrow one of them trucks? Preferably Big Green or anyone?
You should test the 6 speed manual Cummins.
Try turning the hook around and going point first through the smaller round hole lol. Thats how youre supposed to hook safety chains anyways.
Gentlemen, if I may add my 2 cents. I'm on my 3rd Duramax (15, 16, now I own a '17 L5P). I don't believe you fairly tested your Chevy in the downhill/braking portion. The correct method for going down a long steep grade is to have the exhaust brake engaged while using the cruise control to adjust speed. The computer will then control the variable vanes of the turbocharger to achieve the desired speed set by the cruise control. I have traversed many times the same sections of i70 through the tunnel where you perform your tests. I am always amazed how well the truck goes downhill; I often use the term "hand of God" when referring to how the truck responds when I tap down the cruise control to go a few miles/hr slower when confronting the twists of the same road. I never need to apply my brakes, not once.
Often I talk to Duramax drivers at campgrounds who don't know about this simple procedure.
If I may make one other comment. The Ike Gauntlet while being an extreme stress test for trucks is not indicative of how trucks perform while towing on 99.9% of North American roads. Here's my case; last year I bought an '17 F250 to tow my TT. I live in the North East where mountains are less of a concern than out West. However, while towing 10k the F250 could not sustain the set speed on cruise control on even the smallest of grades. If set at 65mph, the truck would slow down on an incline to 61-60 before downshifting to 5th, then race up the hill, eventually speed past the 65 then upshift back to 6th gear. I kindly refer to the Ford as having a lazy cruise control. This is real world driving that no one on RUclips tests. I sold the Ford 2 weeks after, and returned to my Duramax's. The Duramax at most will lose 1 mph up hills and rarely needs to downshift. This post is not a poke at Ford, but a request to conduct tests on how trucks perform how real people use them, not just a stress test.
You guys are great, and I do appreciate all the effort you put into them.
Didn't they downhill test the Chevy 3500 using cruise control? They loved it then. I love the functionality of using cruise control and the exhaust brake when hauling horses down the grade on I-77 in VA/NC (which is about 7 miles) it performs like a champ and the speed remains constant. I don't even have to hit the brakes...They missed this one....
You had a 17 F250 with the 6.7l powerstroke? How did you like the new superduty vs the 17 Duramax?
Barr Thom I liked the technology of the F250 but not the feel of the solid front axle. The worst was the lazy cruise control that couldn’t keep the set speed while towing on the smallest of inclines. That was the deal breaker for me. Sold it after 1 week.
Exactly, that is how this engine works. They are similar to how the Detroit Series 60 motors in semi trucks work with cruse engaged when climbing a mountain. And, yes, if these gentlemen would understand that as a Duramax engine works they are standard with engine braking technology. Therefore, on a downhill application, on Donner Pass where this was filmed, the engine brake would slow the truck down, and a heavy brake application would not be necessary. I have a 2006 GMC 2500 HD with the LBZ Duramax, and that is exactly how it works. Love this pickup truck to death with the engine braking capability. Keeps me from having to hit the brakes.
Nathan is a is a true blue Ram Fan! -- Minus points cause his hooks were too small? !
Why do the comments seem so angry all the time? We are all here to learn about where our money is best spend. I've owned a manual Cummins 24v (I bought this because everyone claimed 20 mpg unloaded...lies! 20 towing and 14 unloaded), I drive both the ford PS 6.7 and we have thousands in our fleet and the Chevy 6.0 not the Duramax. I like the engine and manual tranny on the dodge, the power of the Ford (we don't see many failures on our fleet rigs and they are driven hard), we are moving to gas Chevy and GMC due to operating costs of the diesels over gas, aside from our trucks over 10,000 lbs. I own a Ford V10 that just popped another plug. Lol I am now looking at buying a new diesel tow rig and that is why I am hear listening to all the folks sharing good information.
Sorry 10 towing and 14 unloaded.
Thanks for another video. I don't think most viewers realize how much time that is spent on these tests. I don't know either but it looks like a full time job.
You are right, it’s more than a full time job
The Fast Lane Truck I’ve been a fan and viewer of all your channels for a long time and I appreciate the time and effort that goes into the making of these videos. I don’t know what I would do without TFL
I have been watching since 2010. You guys put so much effort into these reviews and it shows! Keep up the great work!
@@TFLtruck why did you reply to THIS 'soft' comment, but totally ignored the question of why didn't you PROPERLY use the Duramax's exhaust brake? You even said in other tests that different trucks have different methods of doing something, you even said in this or another vid where you compared a Dodge to a Chevy or GMC that the exhaust brakes WORK DIFFERENTLY, but you chose NOT to PROPERLY use the GM's exhaust brake...a bit of bias? NOT A FAIR TEST!!!!!
@@TFLtruck I wouldn't go that far!
Too all of you who care to read this... I've had them all gm, Ford, now dodge.. they all have there ups and downs, can't beat the ride of gm/Chevy, Ford is one hell of a fun truck (fast off the line), but if your in the business of towing heavy loads dodge is where it's at...gm/chev and Ford both started giving me engine and trans problems once I hit 180000km...those are the 2 most expensive to fix..i finally gave up and got a Ram 420000km, 4 years old still going, only wish I had 410 rears truck came with 343 but only did it once so far.. the ride sucks but I'll live with it...all you gm/Chevy and Ford guys got nice trucks but show one that dose nothing but pull 15000lbs to 28000lbs everyday that it gets started in the morning I'm not talking about going to town for groceries or pulling the camper on weekend's
longhaul 7 I too have had all three, while I do not tow 15k everyday I do tow heavy. I can agree about the Chevys ride however, I do not agree about the Chevy and Ford transmissions both are strong and reliable. The only transmission to give me problems actually was the Ram. Had a 14’ dump trailer with approximately 5ton of rock in it and it could hardly get the load moving slipping and shuddering away. Bought the truck brand new and sold it with 23k on the clock
I have 3 of these trucks a 2014 2015 2016. I had to us the grinder on all trailer hitches in order to put the chains on.
I could be wrong but does the safety chains not hook through the smaller front hole in the hitch, and lock into the bigger slot?
We tried both ways
Diesel Enthusiast yup, these guys are tards. I figured that out on mine in 10 seconds.
Why did you compare higher geared lower horse powerd dodge to a lower geared higher horse powered Gm ?
Video idea for you! Many people have said that a newer half ton truck is just as capable at towing as older heavy duty trucks. Do a comparison and see!
I found it pretty impressive that the gmc with that dumb back rack for lights and those A/T tires did that well on MPG even with having to brake and speed up more then the ram.
Andrew Ochoa tune it and it would get worse miles per gallon but it will haul more ass up the hill.
@@thetrollwhoknows9928 the L5B will already haul ass up that hill but that wasn't the point of their test. Every priced tuning an L5B? Someone finally cracked the computers but they aren't cheap.
Picture this guys .. doing the towing test with all the trucks at the same time with the same weight trailer etc .. I think it would be the best comparison it’s not impossible either .. maybe do it late at night less traffic ? 2 extra camera vehicles one in front one behind
You don’t even try to hide the fact that your dodge fan boys how about a real test like more than one up hill run. That dodge trans will take a shit way before the Allison. This truck is better because we say it is. 👌
Yes I just noticed an issues when y’all are driving the Rams, the exhaust break has two modes, Full and Auto. If you were to use Auto mode instead of the full, I believe that the Ram would have held speed the entire way and you would never have to hit the breaks. I’m curious when you drive the Chevy or Ford’s do you use Auto of Full mode on their exhaust breaks if they are setup that way? Also why do you use Full over Auto mode when running these tests with the Ram? I use Auto on mine when towing and have found that it grade shifts a lot better then when using the full mode.
Gm has had that problem with the holes for chains for a while now, family member put heavy duty shackles on there because the hook wouldn’t fit
Adding shackles was the cure I was thinking since their hooks didn't fit, not an issue for most to worry about.
I think you guys should try and come up with a different test because the trucks are so evenly matched that anything could cause a few second difference. Thanks for the videos guys
The Sierra had more power, better fuel economy, quieter interior, and better ride but lost. TFL is far too biased with their reviews.
Mark Holing sure bud it still sucks dick
You guys should do a segment on these SUVs’, 2018 Ford Expedition, 2018 Lincoln Navigator, 2018 Chevrolet Suburban, 2018 GMC Yukon Denali, 2018 Cadillac Escalade
Pretty hard to argue the results. The GM does in fact look like the big brother of the Honda ridgline, the rear end gear ratios weren’t even close, ram was down on power compared to the gm but was still quicker, .1mpg difference could well be in the computer and I’m surprised they didn’t actually use the fill up method to confirm mpg. The fact that a HD truck can’t get a hitch that will accept your basic safety chains is completely unacceptable-I totally agree on the subjective scoring on that point. Looks like gm is slowing going away from making an actual useful practical work truck and catering to the grocery getters of today’s generation. From the solid axle, to the simplicity of an inline 6, to a masculine truck design, ram has it covered. Sorry GM fan boys lol
do a truck match going up the ike gauntlet side by side race
Life exists beyond that damn ike gauntlet, so sick and tired of the stretch of road
Yeah but pulling the flats is easy and it doesn't make for good TV.
Going down grades is the l5p strongest asset. You guys need to review your technic for a zero brake application down steep hills.
It’s distributing. Distribute. Not distri BUTING. Hurt my old ears. Ok, back to watching.
when think about Dodge is there so cheaply built the interior of the trucks use cheap molded plastic on dashboards some of the trucks I've been in the liners coming down just not really good quality built trucks... They're quick as hell but I paid extra for GM quality
and if you ever had to change like the light bulbs or parking brake lights in a Dodge is a pain in the ass compared to like a GMC.. the spare tire holders a bitch to get to.. but I do got to say good V8 Dodge engine sounds great with some like 60 flowmasters on it
I wish the audio was better.....great video again.
No matter how they try (GM with the Isuzu Duramax), it will Never out-perform the American Cummins in a Dodge. Don't believe me, no prob. Go to ANY rural farm town, you will see 2 types of trucks working hard on a farm. Fords, and the mighty Dodge. Nuf Said. The Chevy's are to take the hey to the cattle, or drive to the real work trucks.
robert Burks I own a 2019 f250 diesel but have to tell you, you need to drive out in Amish country ...those guys have so many duramax L5Ps it will make your head spin. And they all work like dogs. Yes there are Fords and Rams sprinkled in but it’s L5Ps everywhere you look here in Ohio’s Amish county!
Brake applications were driver induced. All you need is one light press on the pedal. You were holding the brake too long. This is why you use cruise control and let the computer do the work. You look like Ram employees in this video. Very depressing from a huge fan of the channel.
I love your videos guys. It looks like a lot of fun to do. I noticed that you guys concentrate on the most powerful engines available. However, I know for a fact that a good percentage of trucks sold in Canada and the U.S. are equipped with the base engines. I have a 2015 F-150 Super crew 4x4 with the base 3.5 L Ti-Vct engine. Never once have I ran into a lack of power. Now, I don't have anything to tow but I do haul junk around without a problem. I would love to see what the base engines in these trucks from Ford, Ram and Gm can actually do.
I love both trucks. There both just as badass as the other one. I want both. I love the new Powerstroke Ford f250 superduty king ranch too. 👌
Sorry guys, but you seemed a little biased on this one! Plus, you didn't even use the cruise control and exhaust brake correctly as per the manufacturer for the down hill test on the GM. Should have done your homework a little better on this one!
I-70 east out of Summit. Great test location. That is a hell of a climb.
In the GMC this is the same engine engine brake and transmission you tested in the Super Ike and were extremely impressed and only used the brake once and it slowed you more than you wanted with more weight. This isn’t a fault of the vehicle but the driver not knowing how to tow a load downhill. They have the manual shift feature for a reason, find the gear that works and use it, don’t go stabbing the brakes and then hitting the throttle going down hill.
...thats why I've suggested several times..set the cruise to 50mph ..the truck will adjust itself for downgrading...if then you have hit brakes..take points off
Towing that trailer hooked like that is unsafe. Should have 0 points due to not being able to pull a trailer safely. Just my 2cents. Btw... I have never seen a trailer safety chain hole set up like that.
I bet most of you guys bitching about what truck is the best use yours 90% of the time to get groceries. Ford, Chevy dodge they are all nice trucks and for most ppl do what it needs to do. We have two 7.3 close to 300k and 6.7 with 250k we pull large trailers loaded with multi prep machines all over the country polishing concrete and they pull like nothing granted its not the max but 8k-10k lbs is still a lot for every day pulling. Chevy had a problem but it won't steer me away from buying one. All trucks will have a problem here and there. I even like the new rams just never like the looks of the older ones not saying they couldn't be a work horse. I have 2012 f150 pull small trailers, boats and bed full of shanties does just fine as will dodge and Chevy. 80% of you will not be pulling max tow on a daily basis.
I think you should make 2 runs. One downhill as you do now and 2nd with cruise on. You could take the best or average of the uphill climb as well. It is only 16-minute round trip. This would clear up some of the complaints.
You guys need to get to know the truck first before testing them that hook gets in there no problem and it got the best engine break in its class you guys need to learn how to use it also you were way off on towing it can tow 18.100 pounds get ur numbers straight
So you're telling me an engine brake designed to slow the truck down is getting bad remarks for actually slowing the truck down well? The new brake is calibrated with the cruise so unless cruise is on it will slow down aggressively.
And why are you making a scene over the trailer hitch? It is the same style hitch that has been out since at least 2015, maybe even 2012 when the frames came out. You never seemed to have a huge complaint before.
These videos are starting to show bias and it's not good.
The butthurt is strong with this one :)
Mike Kay chevy girl having a cow because once again ram dominates the diesel market with the cummins engine
Yup that would be a ford broken down
I like all trucks. In my opinion the 2500 series world is an 80 20. that meaning 80% empty 20% towing /hauling. the Dodge, suspension wise is built heavier than the Chevy having a solid front axle but again for 80% of the time riding empty or lightly loaded a softer ride would be more appropriate. also the Gm cost more up front but holds more value in long run. that all being said I bought the Gm and am very happy with it all around. if your towing or hauling more than that 3500 series and up is more appropriate. again my opinion. thank you Fast Lane Truck for your work and dedication.
Two bad ass trucks
I'd like to see some fifth wheel testing. Towing a small but heavy trailer is one thing. Towing the same weight in a 13+ foot tall trailer is a whole different deal. Please test the big 3 duallys with 16,000 lb fifth wheels.
I had a 2014 duramax and had nothing but issues I switched over to a 2015 ram and got rid of the emission and I’ll tell you it’s got 150k and not ones issue
Every hot shot truck on the road is a ram with the Cummins.
because its the cheapest to buy
I've talked to plenty of hot-shotters that have GM'S and Fords. But I estimate that Ram is 50% of hot-shotters, with GM 30%, and Ford 20%.
Could you do a similar test with the RAM Diesel with manual transmission? Would be interesting to see the difference in times.
God damn that ram only gets sexier
These up hill tests are irrelevant! If each truck is able to achieve and maintain The posted speed limit, and you're not planning on going faster than the posted speed limit- the only test needed is 0-posted speed limit. Everything thing else is the opinion of the person driving! That said, I am NOT a fan of GM trucks....BUT, my 2016 ram had to have the trans pulled apart at 19k and now, at 82k....the trans is toast!! The drivers door creeks like a 40 year old truck, my left foot has worn a hole in the foot mat and has also gone through the carpet and now into the padding, the high speed on the blower (a/c&heat) doesn't work, the steering on the truck has me all over the road, I cut off the right front tire because of alignment problems, the metal is paper thin and dents if you look at it hard enough....and the list goes on!!!! I'm unbelievably disappointed in this truck and I would not recommend a Ram to anyone. For the money these trucks cost.... we all get screwed - doesn't matter which pos you buy
for the chevy emergency hooks, just install shackles through the holes and leave them there like what everyone else does
soo that trailer weighs 6000 lbs empty?
I have a travel trailer and a car trailer and both chains hook up to my 16 Chevy. You do have to slip them on a certain way, which watching the video, you didn't do. Also, as others have mentioned, you need to use the exhaust brake with the cruise control.
Was grade braking activated? Hold the tow/haul button down for a few seconds to turn it on/off.
Why don’t you guys use cruise control going downhill?
Why can't the 6.6 duramax in the 3500hd pull as much as other heavy duty trucks ? it has around the same power. It's conventional towing is on par with the other trucks , but not the gooseneck or fifth wheel, which is only around 23,000 pounds, while the Ram 3500 and F-350/ F-450 can tow over 30,000 pounds ?
the truck was penalized because you couldn't work a hook? I admit on my 2018 Chevy 2500 its a bit cumbersome but entirely possible to hook up to every trailer I've pulled
So let me get this right, in a downhill test where brake fade and runaway vehicles is a big issue you downgrade a truck that downshifts and slows you down with little braking. How is that anything but a plus cause you know you can slow down and come to a stop if you need to and you're not going to overheat your brakes. That should have given it a better score.
Does Kent feature on Darius Rucker waggon wheel song video in the pickup?
when are you giys gonna do the Colorado with the 4 cylinder
Why do they keep fartin with the hitch safety chain holes.... Ford did it, now Gm... Like come on, this is basic stuff.
so take more metal off the hitch in order to fit small hooks? STUPID get bigger hooks
I wished you guys SHOWED the GMC, did you use cruise control? Why did the GMC lose points for brakes and tow hitch, but not GAIN points for being faster, quieter and smoother ride?
I also don't think it's fair to test an off road truck like the All Terrain X against a regular truck. The GMC has off road suspension and tires so it's tow capacity is limited.
the ram also had the offroad package. it had special shocks and things as well.
Duramax is just trash compared to powerstroke and Cummings.
@@Fazer1971 lol ok go talk to a diesel mechanic
@@miket2172 lol
You should used the sle z71 Sierra not the Sierra all terrain because the all terrain has heavier tires
I'm a born and raised Chevy guy, but all 3 trucks are badass and have their own ups and downs. It's 100% personal preference honestly. Besides stock power is so restricted with EPA bull shit now days.
Delete kits, exhaust, CAI and tune really wake these engines up and make them beastly trucks. Were talking about 200-300hp/tq gain EASY on mild settings for all 3 brands. That's badass if you think about it. Stock is lame for old farts lol
I get keeping it stock for warranty purposes, but in reality all 3 stock will basically perform the same or close to each other at least. Again pick what you like best, I would buy a Chevy, but that doesn't mean the Dodge and Ford are not super nice and performance/towing beast.
Chris Topher No, your not gonna make that much more power after deletes and tunes. 150 horse maybe.. 200 tourque. Maybe..
And even with that, its only the horsepower off the crank not the wheels.
Yea with some cheap ass hand held programer, I'm talking about an actual custom efi live tune
i agree got efi live for my cummins hauls better better fuel economy
Bradley Goodrich Only? 20 horses make a difference, let alone 150.
I have not driven a Cummins but have an f550 powerstroke dump... just as a disclaimer. I have this exact Sierra(I removed the cheesy bar). Really, it is a modern marvel. Especially the downhill speed control. You really just have to know how to drive it. Basically, you press the brake once, the truck will downshift, and then you can keep an exact speed just by easing on and off the throttle. If you do not give it throttle it will almost stop, at full towing capacity!
The safety chain hookup IS stupid, I rigged some chains and resolved that.
Overall I think it's an amazing machine. I prefer it to the powerstroke. Can't speak for a cummins.
I love how real world owners and mechanics come in with factually based and unbiased comments to which the reply is "Butt Hurt"?
Maybe those saying that others are "butt hurt" should go test drive the opposing truck and talk to the dealership service department about common problems.
The fact that a 3/4 ton GM Diesel has a max tow of 14,500k lbs in a LTZ/SLT platform is sad when a 1/2 ton GM with the Gas 6.2 has a max tow of 12,500. I wanted a L5P until I seen the #’s on GM’s website. I will be sticking with RAM!
Both nice trucks but I'm sure the Cummins will be going up and down hills well after the GM is parted out.
Have you guys ever considered doing some of these tests with viewer's modified trucks? Mainly to see if things like tuning, water/meth make a large difference in the results.
I hope you all get to test some duallys with there v8 gas powertrains. Definitely want to see Ford's 6.2 go against Rams 6.4 in a 0-60 plus GM'S 6.0.
Why did you not use the jake brake on the GMC? You guys don't seem to know a lot about trucks...and you were hitching the safety hooks wrong...try this next time OWNERS MANUAL.
I like that Ram gives you the option for a sunroof at lower trim levels, wish GM would do that.
Both are nice trucks, I'd take either and be very happy. I'd rip that ugly light bar off of the GMC in a second then all would be good.
Thanks TFL for all of the videos you post and taking the time to do so.
I love this show
There's really no competition when it comes to diesel. Cummins reigns champion.
Am I the only one who cringed every time Mr. Truck said “Weight Distribuuuuting?”
Get rid of the subjective scores. Use everything else.
We looked at that, it would be hard to find a scoring system that could take things into account (like the hitch issue) and ergonomics.
Break it down to 5 categories. Cause it’s makes up too much of the score. Grey work men
After 4 super Duties of varying engines I got pissed I went to buy Chevrolet in 05 however they changed to the ifs suspension I'm not having it, I went and bought a Ram 3500 with the Cummins 4 by 4 I gotta tell you I truly love this truck after 13 years of ownership I replace the serpentine belt and a water pump other than regular routine maintenance I use Lucas injection cleaner exclusively as well as Lucas Oil stabilizer with my Rotella oil this truck has never let me down and it pulls 20,000 pounds on a regular basis I guess I'll keep it for another 13 years.
You mentioned only one brake application in the Ram coming down Ike, but did you have the exhaust brake feature on? Curious minds need to know!
You must set the cruise control on the GMC in order for to maintain a certain speed otherwise it will continue to slow down due to auto grade braking
shouldn't you try to get trucks with the same axle ratio?
You can’t get a Ram 2500 Cummins automatic with a 3.73. You can’t get a Chevy 2500 Duramax with a 3.42, so:
1. How do you propose to do that?
2. Why do you think it’s important when the transmission ratios aren’t even the same?
Why? Gas mileage is affected by gear ratio. The test is impossible to do with an apples to apples comparison. Its completely unscientific to do the tests under differing conditions as well (different time of day). There is no "winner" or "loser." They both did what they are advertised to do.
Cummins is a true Commercial grade Medium-Duty Truck engine. Duramax is an overboosted pickup engine that's sounds like a gas engine.
Interesting with the uphill you didn't have tow/haul mode on for the Ram but you did for the GMC. Not sure I understand why?
