All-around it's a great truck. It's new so it's hard to honestly go into much detail.
cons
Gas tank size - I'm comin from an F-150 with a 30+ gal tank. I feel like I'm always filling the Sierra because the tank is much smaller.

The technology on the 2020 Sierra Denali is impeccable. The camera views are extensive and clear. The infotainment system is detailed and user friendly. The additional steering wheel controls are just icing on the cake. In my opinion, excellent vehicle.
cons
The only thins that they didn't add to this model are: the read text feature (had it on my 2015). Then I think they could also add the rain sense wipers.

4 wheel drive GMC AT4 has great handling and acceleration. leather seats are comfortable and has nice accent colors in them. the AT4 seems to have more cabin room in the back and love the tri-fold tail gate
cons
i do not like the auto stop feature which will shut the engine down at a red light or stop sign if ambient temp is cool enough but the truck does have a button you have to push everytime to disable this feature.
