I just got all the different gaskets, replacement window latches, a banana wrap piece, some replacement light lenses, and a bunch of other stuff from Inland RV. It all came promptly and was extremely well packed, plus, even if you don't know exactly what to order, they do. Good outfit, I just wish they had a complete catalog . I got a real nice 12V fuse box from Vintage Trailer Supply too.
Here is a real nice guide on how much seal you need. You can look at the pictures, count the windows, door, and outside compartments in your head. This will keep you from having to measure.
After this seal is replace you need to leave a vent cracked. If you don't and your trailer is air-tight in the summer heat, it can cause the wing window to break. That is a hard window to replace and can be pretty pricy.
Frequently people need more than just a source for a part, they also need a question asked like "This is the part I plan to buy but should I?". For me the question isn't where can I get, Its where should I get. Inland RV, Inland RV, Inland RV.
Just wanted to post a reply about buying Airstream parts from Out of Doors Mart. These guys are really great. I emailed about needing 2 segments for a !987 Sovereign and in just a few minutes I got a reply from Dan the internet sales guy. Few minutes later they were ordered. Every question I sent by email Dan would reply. They received them from Airstream on a Tuesday. Shipped them to me that afternoon (with other parts I needed) and I got them Wednesday. They have a lot of Airstream parts and now sell ZipDee parts. Check them out. https://odmrv.com/
