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.
