Also a hanging floor for a cooler. I made 1.25" slots for the straps to go through and rounded them off with a router. I kept the slots about 1.5" in from any edges and both are still going strong a good five years later. I coated the both with just a canned urethane I had and recoated them once a year till I sold the set up. The guy who bought it does the same. I threw a little playground sand on the top of the floor when it was still wet a few times and that seemed to do the trick. On my new frame I have skidguard plywood and that works great. Two years into it and haven't needed to do a thing to it.
