I had a friend and his wife in the space of 6 months, give, sell, donate everything in there house, sell the house and by a used motorhome. They spent a week in a local RV park and the full timed for the next 7 yrs. along the way the sold the MH and got a pickup and 5th wheel trailer.
they would spend time doing home builds for a organizations like habitat for humanity and other activities.. they did not need to work for money just trying to keep expensive low doing volunteer work.
