Glad you received your part!
I didn't get a chance to go by their shop but did an email exchange with them.
The "Sales" said the following; "We are updating the web site for sales. Should be running shortly. We are not set up for service calls as we are manufacturer and this is usually handled by our customers (read Airstream). Having said that we will handle any calls or emails we get but do not have someone dedicated to this at the moment. Sorry for the inconvenience."
So they are putting the customer service ball in Airstream's court for support on their products. This is understandable to the extent that CATCON folks trained AS assembly line and service personnel on how to install and maintain their products.
Bottom line, the CATCON folks have very helpful to me but when they could get to it. And I could see how a small company could overwhelmed by service inquiries from thousands of customers on components sold and installed by another party.
