Gray water tank

[Alabamamike]

I am new to my 2021 GS Enlighten 20RD and I noticed the control panel in the trailer indicates 2 gray water tanks. Does this unit have two gray water tanks? They sure did not tell me when I bought it.:confused:

If both lights are functional, then yes you have two tanks. The opening for one is usually close to the black water emptying valve and the other is usually on the driver's side under the coach.

What VAHappyCamper said is correct. My 2022 Conquest has the same panel and what you need to know is they use the same panel for several types of units. Its cheaper for the manufacturers to buy 10s of thousands of the same panel than buying 5 or 6 different panels. Mine also has a switch for a slide out which I know I don't have.
BTW...mine new from the dealer seemed to be perfect but during the maiden voyage we discovered that the lights didn't accurately work. Turned out to be just a faulty ground wire that was fixed in seconds.
Happy Camping!!!!! �� ⛺
