You are not that far from the Natchez Trace

Here.It's RV friendly but does have a height limit of 14 feet. My Fifth Wheel just makes it at 13 feet 4 inches. It says there is a 55 foot total length limit, but I'm right at 60 foot and didn't have any problems. The speed limit is 50 mph and enforced. It's a very leisurly drive, so don't get into any hurries. Also, lots of stops along the way for historical information. Great drive! Want to do it again some day.
Hope you enjoy it as much as we did (and still do).
