A lot of people attach the extra valve to the end pipe where the hose connects. Then just open both grey valves and the tanks will equalize. You need an adapter on each side of the extra valve so you can attach it to the trailer and then attach the sewer host to the valve.

I was born with nothing and I still have most of it left.

The idea with that is add that valve to your main drain and close it. Than open both gray tanks to equalize them. I have heard of some that use this to push some grey into the black tank, but I would be afraid of black slashing back into the grey. Probably woudlnt hurt none though. I would only try it if you are positive the black is has a lower level than the gray.

My 29RLDS has 2 gray tanks also. The dealer told me that 1 is for the kitchen and 1 is for the bathroom, seems to work fine so far,
