Inside, the cabin reflects GMC’s commitment to premium materials and thoughtful design. Perforated leather adorns the front seats, which feature both heating and ventilation capabilities. The 10-way power driver seat with lumbar support accommodates long drives, while the multicolor 15 head-up display provides critical information without requiring you to look away from the road.

The HD surround vision system with rear camera mirror and trailer view camera provisions makes parking and maneuvering easier, while ultrasonic park assist takes the guesswork out of tight spaces.

Hitch guidance and hitch view camera simplify hookup and trailer monitoring. The spray-on Bed liner with AT4 logo protects the cargo area while reflecting the truck’s off-road heritage, and LED cargo area lighting illuminates your work space.
