Good lord, it was a joke......but we were talking about RV fabrication shops which is new ones. Methed out fabricators don't have the link to the second hand market, they sell to first time/primary buyers.
I can promise you floridaman is quite well aware of the tertiary 'housing stock' of beat down used RVs. There are whole makeshift towns of the damn things in the desert not far from here.
Anyway, I just thought your initial comment might be an indication of something bigger that I'd seen a small part of: meth in the lightweight side panel glue industry.
However poor quality has kind of been the standard for RVs for a while, certainly worse post pandemic. Which kind of says that manufacturers are shooting for the lowest cost possible and the owners are rather willing to accept it. That isn't exactly indicative of a discerning wealthy consumer, more like an over-extended debtor. It kind of blows my mind that people are willing to spend large sums of money for a new RV. The depreciation rates make buying a boat look like a good idea.
