I think people might be overstating how difficult it is to park in LA. We never have trouble parking our 4Runner anywhere, but an RV? unless it is a regular class B (as opposed to an extended one), I think most of the places would be a no, unless you are willing to park maybe .5 miles away and walk. Hollywood, Santa Monica - those places tend to have pay lots, and even structures (with height restrictions) but go a bit farther into more residential neighborhoods? Should be OK. But, it might require more awareness of the neighborhoods than you possess. I also agree - you should consider renting a car for the week.
