395 up with sights like Crater Lake and the Columbia River Gorge and others on your way to Vancouver.`Then 5 to Olympia and over to 101. In Astoria don't miss the Maritime Museum and Ft Stevens CG. Continue down the OR coast and the CA Redwoods. Just before Ukiah take 20 to 5 and to Sac. 80 to SF and 101 to 46 for the run home.
There are many many great sights on this route. Most of the OR ocean views will be on your right with easier access south bound vs north bound. But reverse this route if desired. Just don't miss the OR coast.
There is only one high priced SF CG located next to a marginal neighborhood. There are many posts on where to stay and how to visit SF so do your research. If you decide to transient SF north/south/Golden Gate Bridge with your rig research this first and I would not take 101, but 19th Ave through SF.
