>>337565>I plan on following 101 for as much of it as possibleI hope you like sharing the road with RVs. In the summer people flock to the Oregon coast to drive their rental RVs for the first time.
I think following the mountains is a more pleasant route. You get loads of national forests to camp in, a few tourist hotspots and miles and miles of lovely quiet roads.
