This helps. I am such a dolt. First trip was Yosemite lakes with a full hookup. Ran a hose for the sink drain. For the shower just on ground. No one knew what or how it connected. A couple of real nice guys at the campground even went online and searched for a manual and said there was no information for the grey water drain. I do know that if you use a real long hose the sink will not drain, or will take forever to drain. So I am going to try the Y connector. The dealer did give me a connector for the hose hookup after I could not figure out the drain connector that came with the trailer. The service guy suggested a length of plastic tubing, but did not say anything about not draining on the ground. Guess I learn all of my lessons the hard way.

Jeanette, I just created another thread with a link to my Amazon wish list for my RV needs. It has a lot of items useful for a new A124 owner. I add to the list all the time. Some items may be duplicated.....
