I've found a truck (88 gmc k 2500) with a homemade wood flat bed, and the guy didn't think to use pressure treated wood, so its falling apart now. If i do buy this truck i'd like to put an aluminum flatbed on it. The truck also has a dump kit on it. Has anyone attempted such a project here? got any pictures? any words of advice? I've got a Lincoln MIG, plasma cutter, oxy-actelyn torch plus an assortment of grinders, and tools. I've never welded anything but steel before. can i do it with a mig? or do i need a tig?
