My dealer told me they called keystone and they said that was the way they were made. Seems grose to me.
Thanks for the clarification from Keystone. I didn't think it was much of an issue until last weekend when I noticed an unpleasant smell coming from the outside sink. There is no p-trap under that sink and when the plug is open, odors come out. There's usually not much of a problem when we're using the trailer regularly, but when it's been sitting for awhile and we come back to it, I don't feel any urge to use that outside sink at all.
Also, since there are 7 of us, the black tank fills quite quickly and I'm also reluctant to use the outside sink for fear of it backing up.
