This was made using 1/2″ thick CDX plywood and aluminum sheeting. I made the wheels by turning round stock on my drill press. The silver frame was made of 3/16″ diameter steel rod.
The propane tanks are 1″ tubing welded to the frame covered with two rubber stool foot pads.
The side wall edges were bent over the plywood. Small brad nails were used to nail the sheeting to the plywood.
By removing the two screws on the rear bumper, the roof panel swings up for interior cleaning.
Ya gotta paint the rims!
