We know several people who have purchased rental RVs in the past, like anything some had good experiences while a few had more issues than they bargained for. Those units you mentioned have very high mileage and should be thoroughly inspected by your mechanic. For us purchasing a rental RV would not be high on our list, we would rather purchase a used unit directly from the owner.
Like many RVs, some owners don't use them nearly enough, some great deals out there for lightly used RVs in every class. Takes a bit of work to keep constantly perusing RVs online, with due diligence, we found our current rig in a neighboring state. Just over 20K miles, interior is in mint condition and full body paint is in great shape, drove nearly 1K miles through 110 degree Texas heat to get home.
