Yes, and there is the problem. I wonder if a lot of the issue is that a sizable fraction of RV buyers are first time buyers. They already think an RV is an awfully big expense, and they don't understand just how godawful the regular RVs are.
Second round buyers buy something else, or stick with what they have and fix it up. I'm buying an Escape because I've already owned a Rockwood. Once was enough. And even so, I can't escape the race to the bottom because standard RV appliances have come through the race to the bottom and won.
It's very different from the car market. Cars today cost a lot more than they used to (inflation adjusted) but they are also much better value. Cars from the 1970s were slow, inefficient, unreliable, and biodegradeable. Part of what made cars better was regulation, but part was consumer pressure. Why the difference.
Anyway, the other difference with cars is that the regular middle class and below are basically no longer new car buyers. Rich people buy new cars, and less rich people buy used cars. This ends up working out because cars last so much longer than they used to. But it is also why you don't see much available in the market that is 'cheap' anymore. People that used to buy a low cost compact have moved into the used market.
