To find out for sure drain your grey and black tanks and put some food coloring with a lot of water in the outside sink and drain again. You better have a clear elbow ( highly recommended anyway) and you will see which tank releases the colored water. The food coloring is save for consumption!

My Flagstaff dumps in the black water holding tank. No need for food coloring, just run the water and you will see.
