I just purchased a 2000 25b21RB and have discovered that the door
leaks. From what I can tell it is leaking through the seal at the top of the door, then through the door before working its way inside.
It uses a rubber gasket seal that goes all the way around the door, but none of the repair places I have tried know what or how to get the seal. Any one have a part number or anything? It looks like the AP Products slide-in seal, but smaller.
