GMC Sierra 2500HD All Mountain Concept
GMC has taken its Sierra 2500HD from merely "go anywhere" to literally "go everywhere". Using the 2500HD Denali Crew Cab as the base, the All Mountain rides on Mattracks 150 Series tracks and has snowboard racks by Thule in the bed. The body is wrapped in GMC graphics with LED lights in the wheel wells and under the chassis. The All Mountain concept shows just how far you can take GMC's trucks.
