I used to do construction work and we used a plastic (fake) wood grained lookin' stuff they called Rhino Decking Boards for decks. I think if you don't use it for anything but a show truck this would be an ingenius idea for an everlasting wood bed. only thing is it's plastic & will scuff really easily so if it's not jus' a show stopper then nevmind i mentioned it lol wink
