Vehicle Description

2026 GMC Sierra 1500 AT4 Crew Cab 4WD for Sale in Mobridge, SD

The 2026 GMC Sierra 1500 AT4 Crew Cab 4WD is built for the kind of driving South Dakota demands — long stretches of open highway, dirt county roads, and everything in between. This one comes finished in Summit White with a Jet Black and Kalahari Accents interior, powered by the available 6.2L EcoTec3 V8 with Dynamic Fuel Management and a 10-Speed Automatic. The AT4's signature 2" lifted off-road suspension with monotube shocks, skid plates, and all-terrain tires means it earns the badge.

The Technology Package adds a multicolor 15" head-up display, Rear Camera Mirror, and Bed View Camera — practical tools for anyone who works their truck hard. Active Exhaust gives the 6.2L a voice worth hearing, while the AT4 Preferred Package brings a Universal Home Remote and rear sliding power window. Off-Road High Clearance Steps are dealer-installed for easier cab access without sacrificing ground clearance.
