To the OP: I'm not sure from your post if you want to run from something ... or to something.
You live in the worst place in CA to be at this point in your life. CA is NOT ONLY - Silicon Valley, Los Angeles, and Sacramento. For instance, my brother recently located a fantastic small town in CA for he and his wife, and his adult kids now live there also. They can walk to town if they want and have a large enough lot for his trailer and pickup - plus a small home in their generous backyard that he rents out for extra income. He does not have his own small business and does not work in high tech, and neither do other members of his family. The weather where this small town is located is classic CA weather - lots of sun with no snow or ice, low humidity in the summers, and (I think where he is) no mosquitoes. So there ARE places in CA that you don't have to escape from - you just have to do some research to find them.
However ... wanting to live for awhile, or long term, in an RV is a whole different thing from living in a stick house ... regardless of where that stick house might be located. Try the RV full time life if you wish, but for those who are used to and maybe enjoy living in a stick house, living instead in an RV would not be a direct substitute. Note especially that if one has any health or medical issues - I would not want to have to deal with them when living only in an RV with no "roots" for good reliable medical help.
