Have grown up working on RV's, Tiffin's are nice, but the reality is they're all pretty much built in the same factory. You want to see crap? Look at something that was just dropped off from the factory before a dealer gets it. Much worse than any car. People bitching about FEMA trailers got to see them factory direct. Make sure you check all the seams, especially at the walls and floors. High leak points are around roof vents and windows. A lot of black streaks are a sign of a RV that wasn't covered or stored properly and may start to have issues with its roof. They all get streaks, but a lot of streaks that are burned in is a bad sign. Like everyone said earlier, make sure your chassis is rated for towing a trailer. Most are just rated for pulling a car or a small cargo trailer, not a car trailer. What I've been looking at recently is a 5th wheel or gooseneck with a living quarters, not a toy hauler. I plan on using it for other things than racing.
