Hey guys I've got an equipment trailer that I need to put a new bed on the wood floor that is on it right now is hard wood probably oak (considering most hardwood beds I've seen are oak). But it's started rotting out and I was hopping to get some opinions about whether or not to use treated lumber or hard wood to replace the bed. Also how thick should the floor be if I'm trying to haul a dozer and a 80 horse tractor on it. The boards that are on it are two inches to three inches thick. There are multiple thicknesses. Let me know what you think.
