Help getting from I-5 to Hwy 101 from Az to San Francisco

We will be traveling from AZ to San Francisco with our 40ft Class A diesel and would like to know which route has the least grade change from I -5 to Hwy 101 in Calif. We will be pulling a CR-V toad. This is our maiden voyage and are trying to decide on CA41-46 or CA152 or I580.

  • Any mountain range between I-5 (interior valley), and 101 (coast), won't be very big. It's the mountain range to the east of I-5 that is the biggy.
  • I recall that the 152 had some grade change but we were headed eastbound from 101 to the 5. The 41/46 should be OK. Keep in mind that the 101 is very curvy and may cause some car sickness but the scenery is incredible. And I wouldn't worry too much about the grad changes in your DP, it'll have plenty of power.
