I bought a 2024 GMC 3500 AT4 with the gas. On Satuday I pulled my trailer with an antique tractor on it for 400 miles over many hills, around 11,000 pounds. Never once did I have a lack of power and towing ability. Held the road excellent and gave overall a very smooth ride. I will say my 2021 with the six speed surprisingly got better mpg pulling the trailer empty by about 2 mpg. Loaded they were about the same but the 2024 with out a doubt has more goose to it. I live in N.W. Minnesota and with my experience will never buy a diesel truck in my area if I have a choice.Too cold. Fuel and filter problems in the winter and diesel exhaust system problems. Last year I received a brand new 2022 105 HP Massey Ferguson tractor and it is now down for the 3rd time with DEF issues. If it weren't under warranty I would for sure delete it. But loving my new 2024 AT4.
High idle switch is used for warming up the cab in the cold. And running attached power equipment etc a dump trailer with a full load getting dumped. Not made just for diesels.
I love the configuration but sorry I’d go diesel . Everything else is spot on ! If I had to make a choice in gas I’d go direct injection. Performance overall is better .
Could have done both like the 5.0 coyote. You get the benefit of direct injection without the carbon build up. However it adds complexity and cost. So it’s a give and take really. Port injection is a little easier to work on as a auto tech
Hey Justin I have to ask you a question do you think a 2021 Chevy 2500 Long bed high country with 30k one owner clean title is worth 60 k with the duramax I hope you respond
JB do you like this or your high country interior better? I saw recently that with the high end GMC the column shifter hides a small portion of the screen when in drive. The screen in the Chevy is just a hair higher and probably not impacted. I really like the way the GMC console flows into the dash though...
Personally I’d rather it have been port injection but probably not for the reason most will say (potential carbon buildup). I’m not crazy about the super high pressure fuel injectors or the high pressure fuel pump that comes with that. Otherwise I have no issue really. Direct injection makes more power and is more efficient. Unrelated to that, but in order to get a sticker for a slide in camper I’m pretty sure you have to have the plow package or the HD front springs/camper package. I have that and my sticker says 2627 pounds.
Great video as always JB and that truck looks amazing!! As to your injection question, Both. I had a cheap ass 2021 Ford Escape that had both but yet my 21 Explorer 2.3l turbo does not. A bit of a head scratcher for sure. Direct will always provide better overall efficiency and power. I put a catch can on my 6.6 gasser to help eliminate oil getting into the intake. Works like a champ.
Direct injection has way more benefits. The 6.6 combustion chamber was designed to keep carbon buildup to a minimum. There are many driving around with over 150k miles with no issues. There are many other DI engines with over 300k miles with zero issues. I would be way more worried about the 7.3 cam and lifter delamination and also the cylinder deck design with the coolant ports that are guaranteed to have issues after 80k miles.
The few 7.3s with the cam and lifter delaminating are ones that are excessively idled, emphasis on the few. L8T is not perfect either and is known for oil consumption and timing chain issues.
I had a lifter failure on my 7.3 tremor at 34,000 miles. Also the 10spd in the ford was terrible and rough shifting. So I’m back in a Chevy. No more ford for me
@@eriktinaj8741 never heard of a timing chain issue on the 6.6. Oil consumption is very few and we’re only on 2020-22. The 7.3 failures are definitely not due to idling, many failures coming out on normally used trucks along with 10 speed issues on 7.3s. The coolant passage design on the deck of the cylinder of the 7.3 is a horrible design and is probably the worst thing on the 7.3 next to the oil pump design with a Jack shaft.
Run 10 ounces of marvel mystery oil to a full tank of 93 octane every tank. You’ll thank me later when you never have carbon built up or a injector fail.
Isn’t it more important to get heat out and away from a gas engine? Seems like the gas engine trucks need the extra hood vent more than the diesel to me.
Update: My 23 Ford F350 build was dropped until 2024, after waiting seven months. I now ordered the at4 3500 6.6 in gas. JB thank you for helping make this decision so much easier.
Nice truck. BEAUTIFUL truck…but why would a dealership at such altitude carry gas tow vehicles? I’m at similar elevation and none of the dealerships regardless of manufacturer stock gas tow vehicles. Great looking truck, just feel it might be in its wrong elements? And no exhaust brake…I’d go Diesel.
Upgrading my travel trailer to a 36' 9" ~8700 dry weight. Looking at 2500/3500 gassers and diesels. Will likely camp 5-7 trips per year. Live in Michigan. What do you all recommend?
Exactly what I’m looking for as well. I think the 2500 gasser should be enough. 3500 in my opinion is maybe a little overkill. I have matched both on prices but there’s only a few hundreds different. As well. I don’t know too much about it but I have placed an order for a 2500 gasser. I hope I can also find a answer!
@@Insima from a cost perspective and gas costs, gasser definitely comes out on top for me still. Just comes down to power and ease of towing. In 10 years it would equate to a $5k upcharge with the mpg savings.
@@Mjwest23 Go big. Go with 3500 Gasser. I’m thinking of changing mine. I see a lot of videos with 3500 rather then 2500 in gasser. I see that the 2500 has trouble when pulling fifth wheels or trailers on uphill and downhill. Compare to a 3500 has a lot more torque and more capacity. I want something for a long run as well.
I'd go with a gas truck as well. Diesels have too many issues, are too expensive up front and throughout their life. Gas engines are fine and will outlast the truck if cared for properly.
I could do away with tech pkg, 5th wheel and sunroof (I have tech pkg and dont really use it, kinda pricey for just software and on new 24s it doesnt change DIC like it did in 23 Not a fan of 24 interior function...love the 13" screen but layout of buttons i didnt like vs 23.... If they kept the 23 layout and just installed 13" screen that would be money.... Owners will see over time that the lights and 4wd buttons and dials are buried behind the wheel and hard to use or see.....HVAC buttons are tiny...i am 6 ft with larger hands/fingers and 23 is better.....DIC I dont really care either way tbh Seen alot of gas builds in higher trims even in 23s....just dont need a diesel and sure others dont as well I wanted a high trim gas and its what i bought.....love my truck still....
Allison was a department of GM my friend……same company at one point. Who do you think owns all the designs and patents on the schematics of the transmission lol. That’s correct…GM. GM sold Allison and now it is its own stand alone company. Go do a little research before you sound like a bafoon! This is the most ignorant talking point among fools who don’t understand. Yes….the current Allison is the branded name only….but it’s all the same designs..parts …schematics etc because the engineers for GM have all the same information to build the new 10L1000 which is a fantastic transmission. Do you think Allison would trash it’s name by allowing GM to put its name on the trucks if it wasn’t a legitimate solid transmission that is built off the same designs. Trolls….they get dumber and dumber
@@justinnieves984 Ford has its own 10 speed in the heavy duty truck. Ford and GM collaborated in the same 10 speed with the their half tons. Allison is only put in Chevy/GMC trucks heavy duty line.
Direct injection is better BUT you need a catch can ( Easy install. GM should have them from factory but you know GM, cheapest route... ) or your intake valves get all carboned up. @mattdagger1480 down below said what I was going to say next

port for longevity, direct for power, both at the same time would be ideal.
JB you mentioned that this vehicle has the high idle switch. What typically is the high idle switch used for? Thanks
Both, direct injection with auxiliary port injectors. Few engines are like this.
Could have done both like the 5.0 coyote. You get the benefit of direct injection without the carbon build up. However it adds complexity and cost. So it’s a give and take really. Port injection is a little easier to work on as a auto tech
GM could have made the hood scoop functional, who doesn't like a good ram air system.
I would of paid for that option.
Surprised it does not have a higher payload - just a 100-200 lbs more than diesel.

I've towed big items with a gas 1500, the 6.6 can totally get the job done if you aren't towing constantly. Diesel just isn't necessary for everyone

I added a PCV reroute to catch the excess oil and carbon. 3min install $150 to keep those injectors clean.
Or ECM controlled solinoid valve for oil pressure.

That's almost exactly the same truck that I want.
My 6.2 LT1 has direct injection and it performs just fine, but I wonder if it could be modified and swapped with port injection… hmmmmmm
Run 10 ounces of marvel mystery oil to a full tank of 93 octane every tank. You’ll thank me later when you never have carbon built up or a injector fail.
@@christopherwilson7698 your joking, right?
Maybe GM should use fords 7.3 cam and lifters too
Isn’t it more important to get heat out and away from a gas engine? Seems like the gas engine trucks need the extra hood vent more than the diesel to me.
Trying to be patient waiting on a F350 Lariat. This would be my next choice of truck in a heartbeat

Great information !
How far can you go on a full tank
Both like the 5.0
Both direct and port together
Wait what? Why can't the truck be used with a slide in camper?

Port injection or dual injection
I have seen many 6.0l and 5.3l with over 300000 miles. Direct injection is better for fuel economy and to make the motor smoother
Why not both?
I think direct injection is better, ideally daul injection.
Port. Simple, reliable, keeps carbon buildup at bay, less cylinder washing.
JB spittin facts, the old GM interior design is “wack”. 💀
Be like Toyota give us direct and port injection

It’s not A Dully
direct injection
Worst thing gm did was combine direct injection and cylinder deactivation
The 6.6 doesn’t have cylinder deactivation FYI
So a massed produced truck is rare🤔🤣🤣🤣🤣
I think he just means a 3500 with the gas engine is rare. Most dealers order diesel, especially with the 3500s.
