Overnight parking for RV

We need overnight, off street parking for our 32 foot RV. The RV would not need to be parked at this location during the day on most days. We would be leaving in the morning and not returning until late afternoon/early evening. We do not need hookups. We take care of our own sanitation and garbage/recycling. We are a middle aged married couple and we both work here in Berkeley. We are clean, quiet and respectful. We are willing to pay a reasonable fee.
