We did Hwy 1 from LA to SF with our 32' towing a jeep.  They were also having a bike stage race at the time we drove up.  From LA to Monterey I would not do again in a MH, but north of Monterey to SF was very nice.  DW and the kids tell me the trip from LA was beautiful, but I was more concerned with staying on the road and not taking out a bike!!  I think next time I'll do 101 from LA to Santa Cruz.
