For heading out into the wilderness (and making sure you come back) the GMC Canyon AT4X is ready to rumble right out of the box. It starts with extra ground clearance and underbody protection, 33-inch Goodyear Wrangler tires, upgraded front and rear e-locker differentials plus Multimatic DSSV dampers. Add nearly every technology and feature GMC offers and you get a rugged truck that never makes its owner to walk out of the woods. This does come at a cost though.
