I would look at a U Haul truck. If they are aluminum floor, I would stay away from them. Anything metal will slide all over the place. We have aluminum floors in our dry freight vans, but we have wooden nailer strips. Actually U-Haul specs their trucks to haul household goods, runs them into the ground and then they wind up in the hands of flea marketers, etc. Penske specs trucks like they spec their semis. They maintain them well and run them a few years and sell them to commercial users. I would certainly look at a Penske before U-Haul. I have bought several wrecked Penske semis for parts because they are speced with premium parts.
