We did that in 09. Was great. We stayed in a Tennessee state park just off of 127 and south of Crossville. Beautiful, well maintained place. It offers fully equipped cabins as well as the RV park. There are well kept recreation facilities, a nice swimming pool (huge) a lake , fishing , etc. A nice place in a nice setting. Built during the depression and they say the job Supt. was Alvin York. As far as the yard sale goes everything imaginable in any condition from rust to restored is available. It was a fun time. Might go again.
Back to the RV part of the park as best as I can remember they all had water and some level of electric service but they were limited on spots with sewer hookups. Fees are quite reasonable. Don't remember fees but we felt they were quite reasonable.
