To conquer the big granite, a rig like Scott Cason's rock buggy is the hot ticket. Cason owns Creative Offroad Designs and he built this rig. "Everything was up to me. I didn't have to work under manufacturers' constraints," he says. The rig has a propane-fed 351ci V-8, C6 transmission, Klune-V, NP205 transfer case, Unimog 404 axles, double-triangulated four-link suspension with nitrogen shocks, custom beadlock wheels, 42-inch Interco IROKs, dual winches and PSC hydraulic steering.
