Fortuna Del Oro, Shangri-La, LaQuinta, Carefree Village, Sunset Palms, Adobe, Sun Ridge, Gila Mountain. Just a few. As you know you are looking at "prime time', but there will be openings do to medical, kids "won't let them go", etc. We have been here since 9-13 and get in several parks and some report "full' but it is at certain times. And like a previous poster stated about RV lots out here in the Foothills. No end to those rentals. Right now most owners are looking for a 5 month deal, but give it to the end of November and into December and no takers, they usually will go to Plan B. Also look at Yuma Craig's List under Vacation Rentals. I sure wouldn't fret about it, as there will be openings, just might not be where you want to be.
