Check the price in your area:

The majority of GMC Sierra 2500HD trucks will spend their lives on the road, carting goods and people between school, work, and places of business, but some owners appreciate the great outdoors and need a truck that can take them off the beaten path. For these people, GMC offers the AT4, an off-road-focused model that allows owners to travel the path less taken. The AT4 adds an Autotrac two-speed transfer case, off-road suspension, twin-tube Rancho shocks, skid plates, a spray-in bedliner, and all-terrain tires for added off-road capability. It also benefits from a set of ventilated front bucket seats, heated rear outboard seats, a front center console, and premium front and rear floor liners with removable carpet inserts.
