Do all Class A gas MHs have generators in the back?

Not all campgrounds have shorepower available. The NYS parks run by the Dept of Environmental Conservation (mostly in the Adirondacks) for instance, do not, while the ones run by the Office of Parks, Recreation, and Historic Preservation (the rest of the state) typically do, including some with FHU's. Nationally, some national park, Forest Service, and BLM campgrounds do not include shorepower.
