I’m a relatively new member, and have found that nobody replied to my post on this site months ago, but I’ll try to help. I moved to the Tellico Lake area of greater Knoxville about a year ago, moving my plane down from the frozen north last November. Hangars are at a premium, so I have my plane, and RV-7A, hangared at Crossville, a 2-hour drive from home. There may be ramp space at some airports closer, and I can only address some airports south and west of Knoxville. Monroe County (KMNV) is very friendly, but is tight on ramp space until their next construction project is finished. McGee-Tyson is probably out, due to excess security requirements. Further southwest, there is McMinn Co. (KMMI) in Athens, that appears to have plenty of ramp space. There’s not much around Rockwood (KRKV) but they may have ramp area. Cleaveland, near Chatanooga, has a bit of an attitude since they call themselves a Jetport, so I don’t know if they would allow operations out of a trailer.
