Is this what yours looks like? 71 31' Sov
Below is a photo of the waste dump connection. I've owned the a/s about 2 years and never had water hooked up nor used the waste system. I'm getting it water ready and don't have a sewer dump hose. I do have a 45 connector, but it wont go on because of the metal plate below the waste hook up pipe. In the photo, you can see the surface rust metal plate, the ground through a square hole cut in the plate, and the waste hook up pipe. The brown you see is West Texas sand/dust, not something gross.
What do I need here?
