If you’re buying an older RV with plans to spruce it up, the starting point will determine how extensive your remodel needs to be. Check for water damage by looking for cracks or ripples in the ceiling, roof, and wallpaper. Inspect the frame and look for breaks or rust, make sure the windows are all intact and that they open and close correctly. You should also test the electrical switches and lights. Most importantly, look (or have your mechanic check) for engine problems. If all of the above seems to be in order, then your update will be mostly cosmetic. Basic projects like adding a fresh coat of paint and updating cushions, curtains, and appliances will go a long, long way.
