Check out Sundance II in Casa Grande, AZ.
CG is about half way between PHX and Tucson. Quiet, 55+ park.
Many of the lots in Sundance II are owner occupied with rv's or attractive park models. Reservations may be available for an owned but unoccupied FHU gravel lot. The short term FHU sites are closest to the office, indoor/outdoor pool and hot tub, crafts, meeting rooms, mail room, scheduled activities, and library. The short term spaces are very clean but unlandscaped and no picnic tables.
Friendly place with many persons returning year after year. All services and many restaurants are in CG. Staff is very friendly and helpful. They keep the place spotless.
