We have friends who own a home in The Gardens in Crossville. It's on Hawethorn Loop, in the original section. A very nice place, in my opinion and the neighbors seemed friendly when we visited. If you can find a home you like and one with a garage suitable for your coach (or have one built to your needs), I think it's a good choice.
I don't know about the tax rates, though. As in Florida, rates vary with the municipality.
