March of this year I stayed 6 nights in LA. 2 days were at Dockweiler RV Park. Great place, right on the beach. Only draw back is it's at the end of LAX. Lot's of planes. If you sleep well, no problem. If you are a light sleeper, could be a problem.
My other 4 days were at the Balboa RV Park in Van Nuys. This par is relatively small and many of the folks who stay there work in the film/TV industry. The owner keeps a percentage available for tourist like me. It was clean and quiet.
One caveat though. It's so tight that if you have a trailer, you drop it at the entrance and the trailer is put in it's site using a fork lift that had a hitch ball attached. It worked for us.
I liked this park because it was relatively close to a lot of stuff we wanted to visit while in LA.
