If you have been to a RV show they have a plethora of entry level campers for young families to get into RV'ing with. Even with my generation out of all my friends I'm the only one that RV's. Not all people like the same things. Look at all the post from people in HOA's and there views of RV's.
Look at the sales numbers someone is buying them. A lot of Bunkhouse models are sold to young families, a few to grandparents.
When I was young I did not have the money to buy a RV. I bought my first RV when I was 38.
Let me ask what age were you when you bought your first RV?
