Darin,
Take it to a trailer shop and see what their suggestions would be. I'm sure if you also looked in the paper or when to Home Depot, you could pick up a metal trailer fairly cheap.
Good luck, looks like a great unit to start off with. That is until you move up to one of our Diamond Plate Smokers
