There’s nothing wrong with buying a used RV, but be careful how old you buy. Some RV parks won’t let you stay in their facilities if your RV is more than 10 years old, and some insurance companies won’t ensure it after a certain age either. RVs also go through a lot when they’re on the road, so they depreciate quickly and older models will have a lot more problems than newer ones. Make sure you know what you’re getting into if you’re buying an older RV.
