Hemet, CA to Klamath River RV Park, CA

I use both Good Sam trip planner (set on slower RV mode) and Google Maps, which has only the faster car mode. I'm taking a similar trip to yours in a couple weeks from now. On the GS Trip Planner (RV mode & allow tolls) from Santa Nella on the 5 to Fortuna on the 101 it takes you across the Richmond-San Rafael Toll Bridge ($21 for 4 axles). If you ask the GS trip planner to avoid tolls, it routes you up to Stockton and then back west on the 37 just above SF Bay to the 101. At about 10mpg the longer route makes the bridge not to expensive. --- Now my wife and I hate San Fran and always try to avoid it. So as some have suggested to take the 5 up by Sacramento and cross to the 101 on the 20 is tempting. But many years ago we crossed from the 5 to the 101 up there (not sure maybe at Red Bluff) and with a big rig it was a long pain, not enjoyable. Still have not made up our mind but the other rig/couple we are traveling with want to take the Richmond-San Rafael Bridge over the bay because of the experience. ??????????
