Just traveled from Grants Pass to Crescent City pulling a 37 foot fifth wheel with a dually. The trip was fine and although the road is a little narrow in places there is room to stay in your lane. In the redwoods close to Crescent City there was one turn with a redwood on the inside of the curve that obviously had been hit many times. I did cross the yellow line a little on that turn. Definitely an okay route with an RV.
