In the beginning it’s a narrow winding road with drops and then you will hit the washboard roads that did have a tendency to jump my Jeep all over the road but when we pulled the small camper it wasn’t as bad but probably a 2-3 rating for that stretch of the road for maybe a mile (is my guess). After that the road was ok. If you’ve ever been to Devils Head around Sedalia, it is like that on the washboard area.
