I'm looking at buying a 25' to 27' travel trailer - not 5th wheel. I want to redo the inside and can do pretty much everything cosmetic as well as basic electrical and plumbing, but don't want to get stuck with a POS on the overall vehicle. I've been researching and have found some pretty good info on what to look for when buying a used one, but wanted to see if anyone has any advice or things you learned the hard way? I know to watch out for soft spots on the floors, water damage, leaks, smells and what they could mean, how to check around the windows and doors, to get on the roof and look around the vents, and the wheels. That's it though. Advice anyone?
