I'm not familiar with So Cal. But up here in northern Cal there is lots of camping that is not in a parking lot. I've been to Bass Lake, it's dry camping but it's in the middle of pines and redwoods, beautiful but hot in the summer. Also above Angels Camp are a few campgrounds that allow RV's not sure of the length limit. I know that most of the State parks have a 30' limit so make sure you check before you go. I hate parking lot camping so I made sure I bought a rig that's under 30'. Though my friend has a 33' and has never been questioned about it when the limit is 30', but 40' they might notice that bad boy.
