These sites are very small and you pay a premium rate.
Looks like the Owner of Pismo Coast Village has the correct information. We stayed there several years ago and absolutely loved it.
Pismo Sands RV Resort, Pacific Dunes RV Ranch Resort, or Coastal Dunes RV Park in Oceano, CA. all have monthly rates off season. Check each website or call them for info. Coastal Dunes is right next to train tracks so word of caution.
they fo offer monthly, but not cheap. pay for the location. and enjoy.
