    You will have 1 tank for the kitchen. The second gray tank is the shower, bathroom sink and washing machine hookup.
    On ours if you are talking about the sensors gray 1 is the bathroom. On the dump handles the first handle on the left is the kitchen.

    Wow... That is confusing... Too bad GD didn't label the Gray tanks as well as identified them better. I will need to run some water down the kitchen sink until the indicator changes so I know which one it is... The open a dump valve to figure out which valve goes to which tank... Wished they had labeled them... Thx for the clues on your rig...

    This varies with who installed the cables and handles. On our 2016 Reflection 337, the front (left) handle was the bathroom/washer and the rear (right) handle was the kitchen.

    To add to the confusion, on mine I have a grey 1 and 2, but also an aux that is labeled as both, Blk-2 on top and Gray 3 on the bottom.

    Pretty sure that is for the washer/dryer setup but still confusing.
