I have had mixed recommendations on traveling east from Willits to I5 South. I am pulling a 34 foot 5th wheel. Any suggestions?

Well, it's always been recommended by RVers, on every RV forum I've belonged to.
And I lived in Napa Valley for a number of years and towed Highway 20 between 101 and I5 numerous times and never had an issue. It's not a fast route but it's the most direct route.
