Stay or go? There's a lot to see and do when you live in an RV and can change your scenery or climate at will. The tax savings alone might be worth it. I bought my RV in March, 2 months before I retired, and registered it in South Dakota using the help of my mail forwarding company.
My Home Address, INC
SD has low excise tax on vehicles, no state income tax and my insurance rates are based on the small town rural address.
The easy thing to do is nothing, but only you can decide if that is the right decision for you.
I have been a full time RVer for 6 years and this is the best decision I ever made. I've seen some of this marvelous country and plan to see lots more. I live in perpetual Spring or Fall weather and RVers are the best house guests because they bring their own house.
I have met so many marvelous people. RVers are generally the "salt of the earth" type people. Their friendliness and willingness to help have made traveling so rewarding.
