Sandev Mobile Park in San Leandro on the east side of the San Francisco bay is quite nice. It is mostly mobile homes but has some RV spots. All spots are clean, wide and well maintained. All sites are back in. They have wireless in the office area, and some sites can pick it up inside the RV. The place is remarkably quiet except for the occasional train, which run mostly in the daytime. IMO, it is much better than constant freeway noise. The place is cash only, $40 a night or $220 a week. I think it is a good deal if you want to go to places on the east side of the bay. The BART station is a couple miles away, and the Ferry from Alameda to SF is a nice ride. We camped here in a Motorhome.
