2015 37KT gray water tank question.

My front gray water tank never has any fluid in it. I thought the kitchen sink was supposed to empty into it. Does anyone have an idea what uses the front gray water tank. Thanks

Drain Tank

I also have a 2015 Thor Challenger 37KT.
The drain tank you are referring to is for the washer (if you have one) The sink water drains to the regular gray water holding tank.

The 2015 37KT has two 40 gallon gray holding tanks. The front one is for the clothes washer, if you have one installed. The rear one is for both sinks and the shower.
