I go through Nashville 4 to 5 times a year, 65 is not traffic friendly anymore like when I grew up there, biggest issue is road conditions, more potholes and patches than I care to admit and traffic well its definitely east coast, Start stop , 0 then 90, then zero again during certain times of the day.
I'd plan my timing where I avoid 6 to 9am , and 3 to 7pm.
If I had to go during those times, I'd remember I'm towing, have a good idea of where I'm going and plan ahead.
Be steady, and leave room to stop
