Tapo Canyon park in Simi Valley is a Ventura County park, you can only stay there for 14 days. There's also an Elks Lodge in Simi Valley with hookups. I agree on the park Balboa/Birmingham in Van Nuys, nothing special at all. There's a park in Northridge, Walnut RV park. Also, there is a park in Long Beach, Golden something, one in Playa Del Rey, Dockweiler Beach RV (not the state park). Check www.rvparkreviews.com. You are going to an area that's not rv friendly and is pricey for anything. Reasonable cost and CA are not possible.
