I wouldn't worry about the younger set, they will find a way to have fun, as they see it. My parents didn't have much money and managed to have a good time. From what i hear the RV industry is showing signs of improvement with higher sales of new rigs. I'll bet they have found sources of financing for the buyers to keep business moving.
I remember the hippie era and they didn't have much money and roamed all over the place and I thought they had a lot of fun doing it. Maybe school bus conversions will come back into fashion, or smaller less expensive rigs. Who knows people adapt to the situation and some are quite inventive.
When in europe I saw that big rigs were not practical smaller rigs or tents were the fashion and some of the tents were very elaborate with rooms etc. The smaller european trailers were very interesting in how they managed the space and ingenious with the use of built in utilities. Those folks have fun and travel all aver europe, there are even camping places in cities next to public transportation so they don't have to drive around the city.
I find that people work things out to achieve their desires, they make adjustments and develop ideas to reach their goals. For me traveling using a tent is not something I want to do now did it when I was younger though and had a great time.
Today's kids have a whole different idea of fun and different goals than we do so I'm not worried about them.
