Your should purchase insurance in whatever state you are establishing or keeping your residency at. If you will use a mail forwarding service, they can recommend an agency as they deal full-timers daily. We are domiciled in S Dakota and used a local agency, purchased our full-timers policy thru Progressive. The agent was able to quote 4 different companies policies. I think they were Progressive, National General, Blue Sky (may not be doing anymore) and I don't remember the last one. Maybe a google search for the state you need.
