My motorhome was plumbed with the bathroom sink going into the black tank. I used a dishpan in the kitchen sink and carried it back and dumped it in the bathroom too. Lots of water in the black tank makes it much easier to get a good through dump of the black tank.
Indeed, many RVs are done this way, for good reason.

Quite common on Class C's and Class A's. On trailers, it wouldn't surprise me in a half-bath.

Little update here...got everything fixed up and also installed a metal tail-piece so they can't get into my trap again. I see all the messages about sinks tied to the black water tank and it was odd to me as well but now that I know, I followed another's post that indicated they turn the outside sink on before pulling out to put more water in the black water tank. I used to sit there with my foot on the toilet supply to add water...SO MUCH EASIER NOW. As indicated, the more water in the black water tank...much easier to get a clean dump! Thanks for everyone's post here!

Highly doubt a sink is tied into black tank, no way.
What your experiencing is hot temps and grey tank is extinguishing odor.
Our grey tank is just as pungent as black tank during hot months.
Just dump a cup of bleach into kitchen sink and let it slosh around during travel......we've found it's always the dish water vs shower water incase you have 2 gray tanks.

Sinks sometimes ARE plumbed into the black tank. My previous Winnebago MH had the bathroom sink plumbed like that. Made adding water to the black tank a cinch. Just turn on the bathroom sink tap.
Don't mistake the fact that you have never seen it as it is never done.

It's done on some floorplans with outside kitchens either because it was required to be done or the builder took the cheap route. In the case of Keystone RV they always take the cheap route and have always done so. This is one sheety situation is it not lol?

From the factory my kitchen sink drained into the 1/2 bath black tank.
I added a seperate grey tank for the kitchen sink

Wow, 35 years of RVing and had no idea a sink of any kind was tied into a sh** tank....how naive is that?
