The math on RV ownership has never been comfortable. A vehicle that costs tens of thousands of dollars to acquire, thousands more each year in insurance, storage, and maintenance, and is actually used three to four weeks annually is not an asset in any meaningful sense. It is an expense with a windshield. RVezy, the peer-to-peer RV rental marketplace that now counts more than 20,000 California owners among its hosts, is the clearest answer the market has produced to that problem.
