I could not find anything in the stores for this purpose so I made my own out of 3" foam, duct tape, and spray contact adhesive. Cost was about $30.00 and a couple hours time. I like it, the Cat likes it, Kelli likes. Everyone's happy. It was easy to make. I do fit a plastic garbage sack over the top for a water proofing for the foam.
I have one from years ago ... and it still works. It has the fill valve on the outside and only takes 4-5# of air pressure. I had it on my old truck and camper for years and it did not rub off the paint.
I also had one that fit on the roof with an outside fill valve, but it disappeared. Wish I could find another one. I also found that after I put the one on the roof, that I got just a touch better gas mileage.
Both of them worked better than the cab over shocks that had to be replaced twice in the 5 years. I had that truck and camper for 12 years and the air cushions worked much better.
