If anyone's main coach door gasket is shot or cracked a brand new one can still be found from Winnebago and isn't that costly. It is sold in one piece and has its own adhesive built in. Just remove the old gasket, clean surface well and install the new one. This gasket is a special profile and molds to the coach perfectly because it is orginal manufacture. That should make a huge difference on the road noise and any water leaks. I will try to find the part number if anyone wants it. I ordered it directly from Winnebago.
