Airstream e-mails:
If you have questions they have a e-mail address.
CUSTOMER SUPPORT, TECHNICAL ASSISTANCE,ON LINE STORE ORDER INFORMATION, SERVICE DEPARTMENT, SALES, and the new SUGGESTIONS all have e-mail address posted on this page below. I will put the link into this post.
Airstream contact page
I would assume suggestion means exactly that a suggestion. Not something for questions and answers. They have provided adresses other addresses on that page for Q & A.
I can tell you I have used that page and gotten answers back from the addresses they provide for customer support.
