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.

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 .

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.

@daryoushborja5115 Жыл бұрын

port for longevity, direct for power, both at the same time would be ideal.

@mattdagger1480 Жыл бұрын

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

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.

@amccauley5033 Жыл бұрын

It has a PTO option.

@Billybob50119 Жыл бұрын

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.

@eriktinaj8741 Жыл бұрын

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.

@Billybob50119 Жыл бұрын

@@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.

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.

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.
