Thor has announce that Airstream has maxed out it's production, and therefore will add, best I can recall, about 50,000 square feet to it's plant.
Increasing the size of the plant won't help, unless more employees are hired, which hopefully will be the case.
While that bit of news is fantasic, it still will take a while for them to get caught up with the back log of windows that have been ordered. Airstream windows are made in the production plant.
We have had some windows on order since this past July.
Therefore dealers are caught in the middle, in that they can't ship something that Airstream can't ship to them.
All any of us can do, is be patient.
If your going to travel and have a broken window that can't be replaced because of the time delay, all you can do is fasten a thin piece of plywood to the broken window sash. Paint it, so that rain will not cause delamination.
