Our Experience here in San Diego CA required a Permanent Home Address for our Insurance purposes and other legal documents. We were lucky to be able to use our Daughter's address. One thing that you want to make clear to your RV and Auto Insurer is that you ARE FULL TIMING, rates and coverage are different than if it is parked somewhere and used a few months out of the year. I have not read the other options here, but for us it was less complicated for DMV, BANKING, INVESTMENTS AND ALL.
