I also added an ADCO tire cover to protect the tires from UV rays.
Cover from the back of the PUP
ADCO cover from the front of PUP. This cover is breathable and will allow water to evaporate from inside the PUP.
ADCO cover supported by the plywood and board.
I cut a section out of a 4 by 8 foot plywood sheet so that it was supported by the tool box and the generator hand rails. Not seen - are two 2 by 4 inch boards that I added between the end of the plywood and the end of the front aluminum rails.
