We just went from Nashville, TN to Franklin, NC on I-40 Eastbound, exiting at Lake Junaluska taking US-23 south. Saturday, 6/5/21. Been both ways on I-40 with a 35' Class A DP, towing. Just use your engine brake.
This route doesn't bother me as much as US-64 from Cleveland, TN to Franklin, NC - sheesh, the curve. It's very scenic along the Ocoee River, but I have driven it once and that was the last time. Same goes for US-74. They maybe okay in the Rand McNally Motor Carrier's Atlas, but not fun in 35' DP towing.
