Maybe if the RV had a "depreciation counter" in LEDs on the side, they could understand what I am talking about. A $250,000 motorhome depreciates about five cents a minute, for the first five years (actually very quickly the first years and then slowing down over time). I would be scary, to be sure, to watch such a clock tick by and run out your bank account over time.
One poor fellow in the campground was starting to feel the effects of time on his RV investment. He had a nice trailer which was now ten years old and starting to show the usual signs of trouble. And he had two tow vehicles, one to tow the trailer and another to tow a flatbed trailer carrying the wife's car, golf cart, and motorcycle. A lot of junk to be hauling around camping. And one of the tow vehicles, a Ford diesel, was firing on only seven cylinders (most likely the notorious cavitation problem with the powerstroke diesels - if you don't add water wetter to the coolant, it cavitates around #7 cylinder due to an idiosyncrasy in the design, and eventually eats through the cylinder wall). So now he has to buy a new truck. Or maybe just make do with less motorized shit in his life. Myself, I would (and am) choosing the latter.
