North Trail Caliber 28rkds Holding tanks

Noobie here sorry if this question has been asked a few times, however I just purchased a 28rkds and I look below I have to separate drain spots, I’m assuming one is for the kitchen galley and the other is for the toilet black water and main gray tanks. My question is in the main drain both have a black handle, short of actually opening to see what flows out can anyone with the same model tell me which one is for the black tank or the gray tank. Thanks in advance Ed

HI Retusarmy54,

Welcome to the Heartland Owners Forum. I expect someone can shed some light on your question about which handle opens which tank dump valve.
