Right now, it's a big blacktop fenced in parking lot with holes in the asphalt for some trees.  It's still fun, a great location by the water and a great starting point to go on long bike rides.  or go to their almost private beach next to the SD Bay.  They just opened a pool and you can ride bikes across the bridge to Campland (Sister resort) and enjoy their full bar/restaurant and live entertainment.  Mission Bay RV is a bit more adult and quite compared to Campland.  They're in the long process of tearing down an old mobile home park on the water.  When that's finished Mission Bay RV will be the best campsite in San Diego.
