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.

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.

Smooth powerful ride, decent fuel economy, expensive but it will be paying back over the years of long term ownership. Longevity is going to be evaluated over time.
