Ours is the Duramax. We traded out Tundra mid road trip because it was struggling with our RV. I am a Toyota guy all the way but this truck has been unbelievable. It is 7700 lbs and we get over 20 MPG easy. If I need to get on it to merge with traffic, it slams you into your seat. I have had over 500 miles on a tank with 240 of that pulling our trailer (and I still had 1/8th of a tank left). Oil change was less than I expected and finding diesel has not been an issue. I know there are significant issues with the lifters in the gas burners but not with the Duramax. Don’t shy away from this diesel truck. Our only issue has been with the nav, it takes some getting used to but once you bend to its will life is good. Hope this helps

This truck is a beast when it comes to towing our 12k lbs fifth wheel. It is comfortable for the family on long trips and the tech inside is great!

Not a fan of the 10 speed transmission

I have a 2022 GMC Sierra 3500 hd pro model. It is a duramax and 10 speed transmission. I plow a bunch of residential driveways and some smaller commercial areas. The transmission is very sluggish shifting back and forth between forward and reverse. Also the transmission starts in 2nd gear unless you have tow/haul mode on. The truck is not bad inside and normal driving. I think there is too much electronic stuff on it like the parking brake and the 4 wheel drive.

Why do they need to to put the running lights on top?? Think it makes it look cheap. Think looks more rugged without lights on top. Fender lights don't bother me although. Beautiful truck.

Only issue I have is not GM’s fault. The emissions system hinders this truck’s true potential. Otherwise it has done everything I’ve ever asked it to.

Great road tractor, with 6.6L Duramax, 10 speed Allison and a comfortable Cowboy Cadillac. Plenty of towing capacity. Barely broke in with 49K miles since new in April of 2021. Sold my 5th wheel RV so no longer need the dually.
