This is what has worked for me in the past. I use 5/8" or 3/4" exterior grade B-C plywood. You have to keep the moisture from getting to the wood. So, with a dry piece of plywood prime and paint it on every edge with three coats of floor and porch enamel. It must be oil or epoxy based paint. I have had very good luck by doing this and get about eight years out of my plywood. I could do better if I maintained the finish and did not abuse the boards by dropping loads of gravel from a tractor into it. If I had just a tow behind gear luggage trailer, I would do the following. Paint as above on one side plus all edges. Then I would bond with contact cement, a piece of textured aluminum sheeting on the other unpainted side. Then I would use an good quality caulk sealer to seal the piece in place. While plastic/vinyl sheeting would work in other parts of the country, my uv exposure would quickly destroy it here. I get snow, rain, cold, and extreme heat here. Pretty brutal climate.
