I took delivery Saturday so I only have a couple days with it so far.
Pluses - The interior is so much nicer than all the reviews I've watched, the 6.2 does have good pickup, the lane departure and HUD is unexpectedly handy. Apple Carplay is great, awesome having waze on the touchscreen split with controls for my audiobook. Seats heat up quick.
Minuses - I wish the truck were a bit smaller - the hood is so high that you don't see corners real well and you're kind of driving through a space from how you remember a few moments before, I wish the outside temperature was on the dash in front of you, instead you have to go to the touch screen and exist carplay, I wish the camera came on with a single button so it was quick to mitigate the bad visibility issue, wife's car has button that turns on surround video immediately, that is nice. It also stays on as long as you're below 15 mph, the camera will just turn off randomly in the Sierra.
Overall the truck is awesome. Easily the prettiest truck ever IMO. I know the reviewers all talk about the Dodge interior but I love this interior
