GMC makes a great, quality truck. The size takes a little getting used to but after a short time you won't want to drive anything else. This is my 3rd Duramax and I'm extremely impressed with how it hauls and drives.

My 2017 (same model) got better mileage than this 2020.....thought the new 10 speed tranny would have made it better. All in all a great truck.

I really like the gas engine in the 6.6 liter. It gives me enough power to haul my 5th wheel and I don't have to mess with the DEF.

Don't Buy Denali HD Diesel GM could design the emissions system to be reliable so buy a ford
