I did something similar to Rex. I have a similar trailer that I got from Harbor Freight. Decking is CDX and I coated it with Automotive rubberized coating. Available at auto stores, walmart etc. Just $4 a can I coated all edges and sides. Then put outdoor carpet on the top surface (not the fake green grass stuff). Also put 4 roller bars on the back also available from Harbor Freight. Loading and unloading is a breeze, rigged for day trips it is a one man job. I also made some modifications to make the deck wider. I can post some pics in a couple of weeks until then it is still folded up.
