Looking for a washing machine drain to RV sewer

[bigtexan99]

I have a washing machine in a cargo trailer.  I'd like to have the washer drain down a garden hose and go into the sewer connection.  I have an available 3 inch sewer line in the ground, with the standard threaded mouth.

Is there a cap for that sewer hole that accepts a garden hose on top?

ah, never mind.  I found it.
