a few of the area's state parks have a handful of sites with hookups, but i'm sure they're already taken. you have to reserve them months ahead, even in the off-season because they are gone in minutes.
Calif. State Parks system has less than 1% of its campsites, with any hookups. most are W/E. and they are usually reserved year-round.
some of the SD county parks have hookups. go to their website and find one.
