Need help with route for noobs - SoCal to NorCal

95, 40, 58, 99, 46, 5, 20, 101 is one route....
This is the way we would go in our rig. I think highway 20 is one of the very few roads over the coastal range that is good for rvs use.
and the others are not bad at all. The descent from Tehachapi down to Bakersfield is the only part that gets a little hairy, and the traffic on 99 is pretty heavy. If it's too much for you, you can move west to I 5, but traffic will be heavy there, too.
