I retired at 53, been snowbirds for 10 years. Early retirement was one of the best things I ever did, We have seen the USA coast to coast and border to border several times. Never one regret. Biggest expenses have been medical insurance and a bad Ford 6.0 diesel. After 6 years we found the perfect place for us and purchased a large RV lot and put a park model & Texas room on it.
Consider deep south Texas, friendly people, low cost of living, lots to do and about 500 RV & mobile parks in the Rio Grande Valley.
