Toilet and sink both into black tank- weird?

[vsheetz]

Our previous coach, a Safari Trek, had the bath lav drain to the black tank. Our current coach does not. And I miss the feature - sure made it easy to add some water to the black tank after dumping.

I am also thinking that unless the drain trap works well, it is probably a good idea to keep the sink drain plug in except while using for odor control.

Both our Winnebagos drained the bath sink into the black tank. I assumed it was simply due to the fact that the black tank was directly under it and the shower, kitchen sink and dishwasher were over the gray.

2013 Thor ace 29.2 bathroom sink drains to the black, it's nice cause gray fills much faster.
