Safest Route Tucson, AZ to Brookings, Or.

[Pacificpilot1]

I'm leaving Tucson, AZ after  2 weeks' delay, destination Brookings, Or. in my 34' Class A, diesel pusher, towing my car. The route over Mt. Shasta is unpredictable. I am familiar with 5 through Medford to Roseburg and 42 across to Bandon, S. on the  101.

The 580 route around San Fran to the 101 looks not RV friendly. I would appreciate any feedback you might have.

580 is a full blown freeway around San Francisco. It can be busy but no concern about driving a big RV on it. The option is 101 through the West Bay and downtown San Francisco. That will be more of a white-knuckle experience for sure.
