We hope to leave Yuma in the next couple of days and head towards Death Valley, Sequoia NP, and the Redwoods NF. Is it possible to get close to DV and Sequoia in a 40' motor coach? Also, is Rt 101 doable in a 40' plus toad north of San Francisco. I'd like to visit the Redwoods on our way to Junction City, OR and don't really want to go over Grant's Pass again. Not that it's a problem but I'd like to see some other parts of our great country. Where would be a good place to cross over to 101 coming from Sacramento? Is it really possible to get from CA to OR from that route?
