Suggestions for Southeast Camping and Boarding

I’m looking for a great spot to camp (32 ft RV and tent) on a lake that is good for boarding in the Southeast. Anywhere in southern Kentucky, Tennessee, northern Alabama or northern Georgia would be peachy (millions of peaches, peaches for me). Ideally, the spot would be secluded and beautiful but also offer all the modern amenities (power & water hookups, shower and convenience store type groceries or better). But most importantly, the place must have a lake with a good boat launch and if not butter, at least lightly swirled margarine conditions with a minimal amount of boat traffic. Is that to much to ask?

Any suggestions, Bueller, Bueller, Beuller???
