We've already crawled all over the GMC Sierra All Terrain HD Concept at the Detroit Auto Show, and Mike Levine from PickupTrucks.com took an extensive look at the interior and exterior with designer Carl Zipfel.

Compared to the Ford Raptor, the GMC Sierra All Terrain HD Concept is a T-Rex. Based on GM’s new Heavy Duty platform, this truck is in a whole other segment than the Raptor and was never meant to be a Baja machine.
