We have a Montana fifth wheel with 2 grey water tanks.  There is only one termination valve to dump the grey water.  We assumed that both tanks were being dumped but when we check the indicator panel it shows one tank empty and the other full.  Are we missing something here?  Does anyone have this problem?  Please help!

I don't have a Montana, however a friend of mine, Mike Kennedy does and he recently showed me how he has to reach way up under the slideout area to release the galley grey water. The release handle was put under there, for what reason, who knows?

Our Keystone travel trailer is the same way. One grey tank and the black tank valves are together in one location and the other grey tank valve is by itself towards the back of the trailer.

You will find the handle for the kitchen tank coming out of the frame in between the wheels on the drivers side of the rv.
