Thank you! Found it! It was the passengers side, but it was in fact a tiny T handle. It just happened to be on the side opposite of where I crawled under the camper the other day.On our 97 Starmaster it's behind the driver's side tire on the end of a line, It's a "T" handle that you pull to open and push to close. The line is about the size of my pinky finger so it takes a while to drain a full tank.
No, we sold it last year. It had a 90 off the drain pan, a vent on the exterior wall, a pee trap, and a down pipe. When we used it I took the large cap off our 25 gallon tote and parked the opening under the down pipe.Do you still have it? Looking for pictures of the plumbing for the shower
I just found that fitting in the camper today while working on it and cleaning up more stuff and I was wondering what it was for! Now I realize what it is tyYes, there is also a fitting you can get to connect a hose to it. The threads were damaged on ours so I could put one on it.
