These would pretty much be relegated to campgrounds in order to have electrical, water and sewer hookups, wouldn’t they? I don’t know of too many undesirables who camp.
Not necessarily. In regards to RVs, there are those that boondock...they camp with solar panels and conserve on water. From what I’ve read, in the southwest especially it’s easy to buy water on tap for say, 25 cents a gallon at a public spigot. Use a dump station for waste once a week or so, and you’re good.
