What people say
I’m not a fan of black. This truck had a black exterior and interior. It’s not for me. GM should offer more color choices.
This truck is an SLT model, so its loaded with a lot of luxury features including power leather seats, premium sound (Bose), factory remote start, heated and cooled seats, heated steering wheel, etc.
The direct injection system and potential carbon buildup on the 6.6 gas V8 engines concern me - especially for long term use. GMC needs to work on developing a more reliable HD gas engine for longevity.
Good towing package/prep and good condition aesthetically. Little to no rust apparent.
Solid truck with plenty of power and all the bells and whistles. Rides smoothly, the Cadillac of trucks for sure.
