The Dirt Heads return as Fred Williams and Dave Chappelle decide to build a four-wheel-drive motorhome on this episode of Dirt Every Day presented by Tire Rack. Starting with a 1975 Winnebago Brave RV, the guys attempt to build a monster house on wheels with 42-inch-tall tires. But will this wacky wheeling motor coach actually work off-road? Or should the guys stick to fishing?
