RV parks On the beach anywhere as far south of Rocky Point to El Desemboque?

Hi! Just found this forum and signed up. I've lived in Tucson for over 40 years and love it, but have been visiting Rocky Point for 20++ years and love Rocky Point too! I'm an old man with a bunch of kids and grandkids but have decided it's time for my puppy, Lily and I to sell our house, buy (another toy hauler) RV and semi-permanently move down that way. I would die to live at the Reef on a beach site, but can't afford to - actually really can't afford to live at any reasonably nice RV Park in RP (a cervesa cost more than in some nice places in NW Tucson now-a-days - sheesh!) So I am coming down to look at places like Puerto Lobos, Puerto Libertad, etc. Can anyone help me?
