[VAC] Sewer adaptor again

[JPPOLLY@xxxxxxx]

RJ, checked out seweroutlet.jpg and it is close but not exactly.  Mine has 4 
protrusions that act like threads (ramps I think someone called them) but 
they are longer than the ones in the picture.  The metal elbow looks nothing 
like the one pictured - has a flange on the end that goes on to the sewer 
outlet and  tapers on the other end.  No  hook shaped thingees at all.  The 
tapered end is probably 3 1/4 minimum OD  and I can't seem to find anything 
to fit over it.  Just rec'd another email that parts can be had from 
Airstream dealer that will make the bridge between my sewer outlet and normal 
easy to purchase sewer parts? anybody have a part # since the nearest 
Airstream dealer is 5 hrs away over a mountain range?
