Full Time RV in North Carolina Issues

I feel for your situation. I am also not aware of the laws in NC, but I do know in NJ and in SC it is not legal to claim a campground site as a permanent residence. "Annual Rates" reflect the right to use a campsite for a full year's time, but there are limits as to how many consecutive nights one may be there. We had a 'permanent site' at a CG in NJ for many years, and were restricted by local ordinance and CG rules to no more than 14 consecutive nights at any one time. The CG itself shut off all water in the winter months, due to weather realities, so living there over the winter would have been a great challenge indeed! We had to live in a CG in Myrtle Beach, SC for almost 3 months waiting for our new home to be finished. There were no children involved, and it was over the winter into early Spring, the 'low season', so we received a very reasonable rate. As Spring Break days approached, however, the rates skyrocketed and the owner told us he 'needed our site for others'. Knew what he meant. He was very nice about it, but we couldn't afford to be there anymore. Have you thought about the possibility of finding a piece of land to lease (or buy) where you could create your own site with water, sewer, etc? I know that is legal in SC. May have zoning issues in some communities, and the cost may not fit into your budget, but there are some who do just that. Might be another avenue to pursue. Admire the thoroughness of your research. Family should come first, and that seems very much like what you are both doing.
