There is another thread (probably several) related to this issue, and one poster has come up with an alternate design that can be made if you have access to a 3D printer.
When the airstream company realizes this they will scratch their heads knowing that customers will shop elsewhere.
Don't be so sure. Apparently, this sort of thing has been happening for many years, the prices haven't dropped, and Airstream keeps selling more than they can make. I think constant maintenance is an attribute of trailer ownership in general - definitely part of Airstream ownership! Some people embrace and enjoy this, others complain but soldier on, and still others will either go from trailer to trailer or else return to staying at motels.
