Black Tank Valve/Discharge Under Coach Rather Than In A Bay?

As a FYI, Forest River Sunseeker and Forester Class C's built since the 2010 or so timeframe have compartment-enclosed dump valves. My '11 also has a removable screw cap in the floor of the nyloplast compartment floor to run a stinky slinky through for full hook-up connection routing. The black and gray tanks themselves are located above the chassis frame and the bedroom/bathroom floor(s), in the mid to rear section of the house in a step-up area inside.

So, there are at least a few C's out there
