RVs depreciate rapidly. RV dealers are not interested in leasing new RVs because they would be significantly less valuable at the end of the lease period.
Given the high price of RV rentals, financing an RV purchase may be a better RV lease alternative. While RV dealerships do not offer RV leases, most of them do offer financing on RVs.
The monthly payment on a 10-year $75,000 RV loan with a 7% interest rate would be around $870, which is the equivalent of one month of rental fees for a small travel trailer.
