2017 Vengeance 377V - Docking Station/Black Flush

Ok all, we just took ownership of a 2017 Vengeance 377V Toy Hauler and we have a few unanswered questions after our first trip out that don't seem to be answered by the manual.

1. The Black Tank Flush located above the Docking Station - it does not seem to actually put water into the black tank to flush the tank at all. Is there a valve or something I am missing here?

2. Docking Station has another Tank Flush located in it, what is that for? It also has a note that says "fullway termination valve" must be in the open position, but what is this and where is it at?

Thanks for any guidance on these issues....Click image for larger version

So here is an update from ForestRiver on the dual tank flush. The one inside of the Docking Station is for the Main Bathroom in the front of the unit. The other Black Tank Flush above the Docking Station is for the Rear 1/2 bath. Mystery solved and they both seem to work perfectly....
