US 101 is fine, albeit a bit twisty in places. Have done it in a 36' MH with toad. I would stay away from SR 1, though, in a big rig. In fact, I don't think 38' motorhomes are permitted on Hwy 1.
The hardest part of your trip will be getting from S.F. across the Golden Gate Bridge. From there on 101 is a great RV friendly route. Just relax and smell the roses from the Oregon/ Ca. border and through Washington. The Oregon small little towns can slow you down to 30-40 mph. There are some great views of the ocean in Oregon but not as many in Washington.
