Hwy 412 and 65 should be mostly good for you. There will be hilly and curvey areas. Road width and surface is generally good. Hwy 62 can be narrow with very tight curves in some areas. Hwy 62 is a favorite ride of motorcyclist in the Northwest part of the state. Having said that, RV's of all type have no problems traveling through the state. Enjoy the scenery.
