Kids are hell, it’s true. At least since 1970.
Rv’ers, defined as anything larger then a pop-up. Fall into the obnoxious folks you describe.
Being older and from Phoenix. There is a road that goes from the far east of the valley heading west that contains hundreds of these RV dealers with a plethora of behemoths, homes on wheels. But I never see any customers at them. Yet they do exist on the road. At least when you or I are on the road.
