Wes: I had asked the same question about the canvas cover that was under the sink of my 17 ACE. The fabric had pulled my sink drain out of the elbow that was inserted into the grey tank and ripped the rubber seal that is over the access opening. In the search box at the top of “Maintenance and Repair” put Steamboat (my forum name) or the thread name which is Under the slide. There is a discussion about the same thing you are experiencing with the cover and drain. Hope it’s beneficial.
