Flush with Two Black Tanks

[allredy1]

My wife and I just bought a 2016 Rockwood 8281WS. It has the 1 1/2 bath setup with a blank tank for each of the two toilets. The black tank flush is working great with the front main toilet black tank, but nothing is getting to the rear 1/2 bath black tank. I have looked everywhere for a valve that will switch the flush from one tank to the other, and found nothing. Just wondering if they didn't include the rear black tank with the flush, or there is a valve somewhere I am missing??

We have a 1 1/2 bath setup in our 30WRKSS. Each of our blank tanks has a separate black tank flush connection. Strange that yours does not.

They likely didn't provide a black tank flush on the 1/2 bath. My Sabre was that way. I bought one and had it installed (which I'm stupid as it was a $30 part and $150 install).
