Sorry I haven't been checking my fotki site regularly. The Merc hauler bed is scratch built. The diamond tread pieces are from an enclosed race car hauler trailer, I think AMT. The rest of it is Evergreen styrene with a winch from a Monster truck, gas can and fire extinguisher. In hindsight I think I made the slope to steep on it....
