Bus Depot does not carry it.

It is an ivory color, cup-shaped, plastic, nipple-endowed, sink-waste collector
piece that attaches the bottom of the sink drain assembly to the drain hose.
The open part of the cup faces up and attaches (by mini wing nuts) to a
similarly colored plastic piece that interfaces with the metal of the sink.
That top plastic piece is in fine shape, but the nipple on the bottom  piece,
where the drain hose attaches, has snapped off the collector cup.  That entire
bottom cup-with-nipple piece (under the wing nuts) is the part I am looking for.

Can anyone help me?  Spouse insists we can't go camping when the sink water
simply emptys into the pantry cabinet.  It makes the macaroni noodles soggy.

Thanks.
