Re: Roads to Yuma
I'm not quite sure what you are looking for, but I suggest that you allow plenty of time for the trip down US101 along the coast of Oregon and northern California, as it is as scenic a coastal area as I know of. The road is crooked and at times pretty steep, but the traffic is restricted in speed so RVs are not generally a major problem in traffic. In most cases the speed limit will range from 45mph to 60mph. At Eureka, CA the route goes inland and I suggest that you follow it as the CA1 route is not a good choice for large RVs. It will still be through scenic areas so allow time for all of it.
As you near the Bay Area, I suggest that you take interstates 580/880/680 route around the city. It is a longer route but having driven a motorhome with towd through the city on US101, there is a stretch of about 10 miles that is on city streets with traffic lights and extremely narrow lanes for traffic. I will never make that mistake again.
The US101 route is again an interesting and historic with many points of interest. At Ventura, I would suggest CA126 to go inland to I-5 and then follow it to I-210 which I then take all of the way west to the San Bernardino/Redlands area where it will empty on to I-10 to lead all of the way to Yuma.
As you head west on I-10 you will pass very near to Palm Springs which has an aerial tram to the top of the mountains that is well worth a visit and also to the north of you will be Joshua Tree National Park which is also a very interesting place to visit and which is worth a day or two visit.
I hope that this is at least some of what you may have been looking for.
