North Dakota camper living too cold for some

I can see that. It takes preparation to camp in NoDak starting in July, and one mistake, and you have no water until spring/summer, or have to leave because the camper becomes uninhabitable.

Even with a "four seasons" rig, it will still require skirting, heat tape, heat pads for the propane tank, and many other items to keep all the plumbing above the freezing mark.

There is an oil boom here in Texas as well. It may not have as many openings, but dealing with occasional sub-freezing lows is a lot easier in a RV here.
