Three forths of the RV manufactureres closed their doors in 2007-2008 when the banksters were looting the economy. The few companies that survived have been able to acquire the facilities and tooling for pennies on the dollar.
This has happened in many industries and in my own experiences the end result is an inferior product and inferior customer service and support as their is less competition. The myth is that capitalists want a free and open market when nothing could be further from the truth. Capitalists love a monopoly as that is how they can make the most money and nothing else really matters.
There can be multiple benefits to buying an older product that was produced before the takeover as it will often be better built with fewer corners cut for short term profits.
One notable exception in the RV industry is with Airstream trailers. They continue to make the best RV one can buy. They are more expensive but with them you definitely get what you pay for and end up with a trailer that can last several lifetimes. They stand apart from the rest of the industry.
