Having taken a tour of the Airstream factory in Ohio, I would basically agree - and echo the statement that even Airstreams have problems. We were impressed by how the trailers were put together in a Forest River factory - until we visited Airstream. There is a definite difference.
Interesting observation about the factory tours. Me? I would be far more interested in what comes
out of the factory than what is in it. And what comes out of the Airstream factory clearly is
not in the same hemisphere as any box trailer. No rubber roof, no sidewalls to delam, almost forever aluminum sides and roof, etc. What is really different is that Airstream is considered to be a luxury item that happens to be an RV. Kind of like a luxury yacht that just happens to also be a boat. I have no Airstream in my yard, nor do I have any financial interest in the company. But, I can certainly understand what comes out of the Airstream factory is longevity and quality and what comes out of most box trailer factories is something that is barely able and
might last the length of payments. And they are intentionally made that way with marginal axles, tires that are near or at their max carrying capacity, rubber roofs that last 12 years, filon sidewalls, and sometimes shoddy workmanship. Everything has a price point and consumers drive the quality when all they want is something reasonably nice to camp in that is inexpensive. And they get it!
