Yes I believe so.
Why do people answer when they don't know? Does Google still give you points? They should filter out all the i don't knows. Including this post... You better call the ranger during business hours. They would know whether there are any rules related to that and whether they have seen it done. Google "glamping San Diego" to find companirs that do this, and ask them as well where can they provide their services...
I don't know either
I really don't know about that. I've never used a rental RV. There are RV rental companies in SD though. Maybe contact one and inquire.
