Kampy1, how big is your RV?
There is a RV park in Orange, CA, called Orangeland that is 18 miles inland from Newport Dunes. The spaces aren't huge but we had room for our awning.
The only other place that we've stayed is the Mission Bay RV Park, in San Diego.
A lot will depend on the size of your RV, there are State parks along the ocean at Carlsbad, CA.
Good luck,
MM.
