Check the KOA's in Cherokee, Asheville, Boone and Fancy Gap Virginia (just across the NC line on the Blue Ridge Parkway). There are also several Jellystones (Cherokee & Lenoir). Mile High Campground near Cherokee has been getting some good reviews, but there are no hook ups. There are several Federal campgrounds on the Blue Ridge, but no hook ups. Stone Mountain State Park is a good one with water and electric.
See if this
link will work for you...each red dot is supposedly a campground.
