replace coroplast with steel/aluminum

Dan, I built new wheel wells for my old Starcraft. The originals were destroyed by flats and spinning belts from a previous owner. I threw out the plastic remaining, built a wood frame above the wheels, put aluminum panel in the corners, and installed 404 steel sheets, glued and screwed on to the wheel well frame. 404 is what they use for garbage truck compactors and Humvee armor. I feel a lot more secure with that above my tires.
