Welcome to IRV2. We live in Virginia and have traveled in our RV in the southeastern states extensively. Unless you are really set on spending your winter in eastern NC, I might suggest you consider Myrtle Beach, SC. A lot of folks from up north spend the winter there. It is not far from NC but it has a lot to offer. Plenty of RV parks that are open year round. You have your choice of several nice RV parks right on the ocean and several that are in the area but off the ocean. There are many things to do in the area. Charleston, SC is a day trip away.
While not as warm in the winter as places like Flordia, it will be generally warmer than much of NC. I think you might also find many of the nicer RV parks in NC closed during the winter.
Just something to consider.
