You'll need a domicile. The three favs among full timers are Florida, Texas and S.D. due to no State Income Tax, no or lax vehicle inspection and liberal residency requirements. However, look at all your financial and insurance needs before deciding. You'll also need a professional mail forwarding service. St. Brendans Isle (FL), Escapees (TX) and America's Mailbox (SD) can assit you in setting up residency and provide excellent mail service. The next best advice I can offer is to slow down, take your time as you move about the country, as there's a lot to see and experience. You're not going to do it in a year or two. Good luck.
