2015 26V Impact toy hauler.

[Sparke]

Hello All,
Purchased a new used keystone and have a question for you all.
Do I have one or two grey water tanks? I know this sounds crazy and I’ve had a few TT in my day but my control panel says two, I’ve only found one drain valve but we where doing some boon docking and the kitchen sink would not drain until I drained some of the grey water but the bathroom sink and shower were fine. I also had filled only 50 gallons of fresh water and there’s no way I put 35 gallons into the grey tank.
I’ve searched around forums but I got nothing.
Thank you

If you only have 2 pull handles then I’m betting you only have 1 black and 1 gray.

I have seen bathroom fixtures drain to a black tank depending on location of bathroom.

Probably 1 gray and 1 black. Could not find reference to a "26V", they all have 3 digit numbers so here is a 260;
