I'm Nocal, but I think Naciemento is awesome. Anywhere on the Parker strip on the weekdays rocks, party hard on the weekend. Parker has a casino with nice docks, so something to do if the wind kicks up. It has nice RV parks with full hook ups. Camping in tents, if you don't mind RV pads to set up.
Shasta is great also, lakehead has a couple nice RV spots, and some nice camps also.
My fav is Stoneyford. No campgrounds, no launches. Just set up camp on the beach and party. Make sure you have a good launch vehicle, because there are no launches, you launch on the shore line. Kinda small, but the wind doesn't seem to get to it as it sits between hills. Weekends are very skiable, compared to my home (delta)
