Used my 2021 Montana 3761 Fl that I bought used this weekend. I have the same question. The tank flush inlet on the left, I assumed that was for the fresh water tank? The only reason I ask is the inlet on the right says black water 2 tank flush on a sticker underneath the valve? So you're saying the flush valve in the left that says tank flush is for black water tank 1? Does the fresh water tank not have a flush? Thanks.
