Chattanooga is a beautiful town. My suggestion would be to not hangarat CHA, but look at one of the numerous smaller outlying airports that would be much more GA and RV friendly.
 
We have flow into 3M3 to visit my in-laws who live only a few miles away from there.

Check with N2Prise, he lives close by.

Besides being a cool town, there are a lot of small airports and some good places to visit.
