Newbie looking to buy fifthwheel toy hauler

Had a 27 ft tahoe 5er. Was good at the time, towed over 40k including rain, some snow, wind. All troubles described happened. I also has a wall slightly start to bow near back ramp. There were small metal angle iron pieces welded to the main chassis that were supposed to be used for holding thE walls. Insufficient. Perfect size tho, and I really had no need of separate garage.no smell if you run your engines out and shut off fuel.good luck. Fwiw mine had aluminum skin. I have a funmover motorhome now but will be looking at a vrv if ever in market.
