yup, the RV would be a home on the road for a year or two between the current residence and the retirement residence in Texas.
sell one house, no taxes or upkeep (too lazy to have a rental place and put up with tenants), travel in the RV for a year or two (until I tire of it, maybe a month), then sell the RV and move into retirement house in Texas
if I'm vacationing, a Holiday Inn or AirBNB for an extended stay is preferable.
