Just made the trip to North Carolina and back to Tennesse this weekend in my wife's vehicle. I took US 25/70 E from Newport, Tn through Hot Springs, NC and Weaverville NC to I-26. According to the GPS, the trip was 30 minutes longer than the normal I-40 route. I saw a few RVs, but not could count them on one hand. The road is mostly 2 lane and winds across several step grades. If I were towing, I think I would take the I-81 to I-26 suggested route. However, it sure was a beautiful ride this afternoon!
