I highly recommend OBX Campgrounds on the Outer Banks of North Carolina. It is a fairly new campground.
They have 56 sites, only for RVs, no tents. Each site has a full hookup including cable, electric, water and sewer. Each site is level and has a gravel base. Being new, the bath houses are very nice, clean, with lots of room in them. Only a few sites have trees, the rest are open, but there is plenty of room between each site.
We stayed five days in October 2019. A transportation vehicle is needed to go the the beach and see the sights in the area.
