Warriors Path is in Kingsport and is an okay place. Sites are close, and not real private, but it is state park and is woodsy. There is also a place in Bluff City (about 15 miles away) on Boone Lake - Lakeview RV Park. It is a commercial park, but gets really good reviews.
In Virginia, Natural Tunnel State Park is about 17 miles from Kingsport, north on Rt 23 (I-26) and has large sites, water and electric and newer campground (Lovers Leap) has newer bath house with individual showers and laundry facilities, 30 and 50 amp. Older campground (Cove View) has 20 and 30 amp, but all pull-thrus (not suitable for large RVs.)
Sugar Hollow Park is in Bristol, Virginia, about 20 miles further up I-81 (exit 7) and has a few sites with water/electric.
