The AT4 Premium Package distinguishes this truck with unique styling and functionality. The sport step provides easier entry and exit, while the AT4-specific grille, lighting package, and premium floor liners underscore the truck's purposeful design. LED cargo area lighting and the spray-on bedliner with GMC logo complete an exterior that's as practical as it is distinctive.
