there is this little lockable door. and it has a spongy disk to block the air into the pipe when the door is closed. the spongy disk is moldy. where do I get a new one? 2006 Itasca 29R thanks all
No joke, ask a pharmacist (chemist) for one. Foam is the new rage replacing cotton for stuffing medicine bottles. The bigger jugs of meds come with impressive size discs, and it's all FREE!
