Full-time RV life after retirement often ends within the first two years. Health care is a frequently cited reason for returning to a fixed home. Medicare Advantage plans use networks tied to a home county, so routine specialist care on the road is not covered. Original Medicare works nationwide, but Part B costs $202.90 a month per person, and a couple pays about $4,870 a year. Selling a house and buying an RV also means absorbing steep depreciation and facing higher home prices on a buy-back.
