2026 GMC Sierra 2500HD AT4 Crew Cab 4WD for Sale in Mobridge, SD

Serious towing muscle meets off-road-ready hardware in this 2026 GMC Sierra 2500HD AT4 Crew Cab 4WD. The 6.6L gas V8 teams with the proven Allison 10-speed automatic, a 2-speed Autotrac transfer case, and a Traction Select system with Off-Road and Tow-Haul modes — exactly the combination ranchers, contractors, and trailer haulers across South Dakota and North Dakota count on. Skid plates, all-terrain tires, and red recovery hooks back up the AT4's rugged looks with real capability.

This Sierra 2500HD is loaded for work and comfort alike, with the Technology Package adding a rear camera mirror and multi-color head-up display, plus the AT4 Preferred Package, a dealer-installed Gooseneck/5th Wheel Package, and a Hitch Package. Finished in Sterling Metallic over a Jet Black interior with Kalahari accents, it pairs heated and ventilated front seats, heated rear seats, and the GMC MultiPro Tailgate with the hauling hardware to get the job done.
