In Yuma, the Foothills section of the county has hundreds of private lots for seasonal rent....usually 60'x120' plus/minus, mostly fenced and gated, gravel pads, sometimes some concrete, sometimes the lot contains a Casita, landscaped, paved streets... all lots are designed for 2 FHU RV's to share the space. Water, power, sewer, and garbage service is usually provided. Price range is $300+, depending on area and amenities. If you don't like the cramped conditions of the average RV park, don't want/need the usual park amenities, then these lots are perfect.
