We live pretty close to the area and frequent it often. The problem is finding a campground with both full hookups and space/privacy. In short, it doesn't exist in the immediate area. Your best bet is to find something in the Townsend area, but it's a good 45 minutes to the Pigeon Forge/Gatlinburg area. Even then, you won't have much privacy, but it's better than other areas where you are packed in like sardines (like Claboughs). We've stayed at Tremont Outdoor Resort and like it fairly well, but again, not much privacy. I've also stayed at Up the Creek in Pigeon Forge and their sites are nice and a little more private, but no bath house, pool, etc. if those things are important to you.
