As for our tank confusion ... We only have one lever underneath up front and it’s gray in color. There is only one in back as well and it’s black in color. We were told that there are 2 tanks up front where the full bath is (1 black/1 gray) and only one tank in back where the half bath is (gray/black combo). The control panel has both one gray and one black handle(s) for draining.

How do we drain JUST the gray tanks with only one lever underneath to open? I have pictures if it helps.

Been trying to search for videos of tanks being emptied but haven’t found any yet.

Really appreciate all the help! Aside from this confusing issue, we are loving everything about this Montana!

Have never seen a grey/black combo tank on a decent sized rv. If a single dump, guess you cannot dump just one or the other.
