My suggestion is to visit http://www.rv.net/forum/

They even have a section on "Full Time RVing."

There is an organization for full timers that provides info on issues like taxes, voting, an address etc. I don't know the name of it but you may find it on the rv.net site or search the net for it.

I'm not sure I would sell the house until I had been trying the full time life for awhile. You may find it is not for you.
