Perhaps this is a good example where so many complain about the "quality" of campers being so cheep but those same people who complain are not willing to pay the price for a higher quality camper. Monaco RV's are not cheep, but they are, what some would call "quality". Quite obviously, those folks who complain about the "lack of quality" are not willing to pay the price for it, causing this company, who do just that, are forced to close down, probably due to low sales. 
There has to be more to it than quality.  Airstream has been around eighty years and not closed it's doors.   And they are not inexpensive.  And customers purchase every one made.  The issue here is more likely management 'right sizing' shifting to more profitable units, and perhaps with less competition.   I do feel for the employees.
