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.
None of those roads are bad. 41-46 is a long two-lane road that can be prone to having a lot of traffic depending on day of week and time. It's the main route for everybody from Fresno to Bakersfield to get over to the coast. 152 is mostly freeway all the way over but changes to 2 lanes for the last few miles into Gilroy. I580 is also freeway and only goes up to 1000 feet. It is four lanes wide at the steepest part. 580 also has a LOT of construction going on right now and depending on time of day it's a major commuter road.
