Just curious. Is it less hilly to travel 460/19 then to Abingdon and hit I81. or is it better to stay on I77 to 81S towards Knoxville. Pulling a 30 ft TT

In West Virginia I would stay on the interstate if you have a big trailer. Most other roads are very hilly and may curves.
A few years ago we traveled from Knoxville Tnn to Beckley West Virginia and took the interstate all the way. When we did some sight seeing around Beckley and saw the local roads, we were VERY glad we never tried them with our trailer in tow.
