What RV'er uses the word "Spectacular" for a bathroom? Gotta be an ad.
My parents lived in Seymour TN and when we would go visit them, and after mom died, we always stayed at Riverside in Sevierville TN. If I was going to go back, which I'm not, but if I was..I'd stay there. Get a site up on the river. It's under the trees and we just loved it. I always decided at the last minute to call work and tell them I was going to be a couple more days. It's not a super fancy campground, gravel drives, dirt spaces, etc.. But, it's clean, the rules get enforced, dogs welcome, openly Christian and friendly.
When mom was diagnosed with pancreatic cancer we needed to be near her home and the UT Knoxville hospital a lot. They offered us a special deal to store the RV there so we could just drive the car back and forth (from central NC). She died before we got to use it but, they were generous and caring people. In that area my choice will always be Riverside RV park.
