For the sheer beauty of it, i would recommend taking 80 to 101, yes, through San Francisco. You will need to time it for mid-morning, and you'll essentially have the route through the city, and the bridges, to yourself. The views will be guaranteed E-ticket! Be vigilant about maintaining the center lane when on 101 over the surface streets - Van Ness to Lombard. If you want to visit San Francisco, you can find camping across the Golden Gate in Marin County, and drive the toad to the ferry for a ride back into the City. There's no parking for the motor home while going through SF.
I also suggest taking California Highway 1. Do not let hearsay intimidate you. I recommend going over to 1 just north of Santa Rosa at Highway 116. 116 goes through the Sonoma Wine Country along the Russian River. There's great camping west of Guerneville, near Jenner and the junction of 1.
1 is spectacular. Don't miss camping at least one night at Westport Union Landing State Beach, where the Lost Coast begins. This is also the point where 1 turns into the Redwoods. True, it is full of twists and curves for about 20 miles, but the scenery is sooo worth it. There isn't any traffic, really, so the road belongs to you through here, and you can comfortably drive and sightsee.
You rejoin 101 at Leggett. Another recommendation as you drive north is that you exit at Myers Flat and drive the Prairie Creek Redwoods loop. There's also camping at Prairie Creek. The Park Service has a welcome center and other amenities. The drive through is stunning, with many places to pull out and marvel at the trees. Further up 101, Mill Creeek Campground is a nice campground to anchor for the Redwoods, as is Jedidiah Smith.
Be aware in Crescent City.
We did this trip in a 37' Pace Arrow with a toad, so you have no excuses, lol.
