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 can't stay on the road. It's already killed a DPF and had to have a break pedal assembly replaced! less than 20K miles - what a joke. BTW - that DPF takes 30 days for a part from the factory.... My 2003 still has both of these systems operating from the factory with over 300K miles hahahahaha

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.

Just purchased a 2024 GMC Sierra 3500 for the whole purpose to pull our RV. Problem exist where the GMC errors out and disables brakes while driving. Inconsistent behavior. Always connects and remains active until something happens that it senses an issue and disables the trailer brakes. Odd that it reconnects the brake when vehicle comes to a complete stop (0 MPH) and/or put into park. GMC is blaming the brake actuator manufacturer. However, my RV worked fine on my 2022 GMC 2500 with no errors. GMC is basically saying it’s not my problem and produced a bulletin which pretty much blames the brake actuator simulator and says they are clean. I argue there are probably others with the same issue using an electric to hydraulic brake system. I also argue that to put this bulletin out after my purchase and my issue is bad customer service and support. If they don’t work with all third party manufacturers they should say that up front. So if you want a truck for pulling RVs without conditional parameters that are not publish, look for another truck. I gave a 3 because other than this trailering brake issue the truck performance is spot on. It’s a shame their engineers are ignoring this problem and left me to work around.

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.
