Boy that is a big ?
1/ do you still live in a permanent residents? the feds and insurance health, car, RV all require you to have one on paper or a real one. There are several Co. that you can work with to use as a mail address/residents. they are located in South Dakota, Texas, Florida. If you have a family member that will let you use there residence for a home address this will work also.
2 Most car/trailer insurance Co will not insure you. check with your current provider. Be very careful to not tell them you are full time right now but just checking what they can provide. You may get insurance dropped if you say you are. Good Sam's and several others will insure you.
3 health care insurance you will need to have a policy that is mobile from state to state most policy's will not let you move around the US and cover you.
4 Use you tube to find posts on full timing. you will have to weed though some of the BS that is out there but a lot of good post's. This forum has the same problem!
hope this helps Tim
