They should be the same size, so I would think divide the total by two.

The Montana website (http://www.keystonerv.com/montana/#/specs) states there is 93 gallons of grey tank capacity. We know there are two tanks. One (shower) is mounted longitudinally in the drop frame section and the other (galley) is mounted transversely in the upper section. One can assume they are equally sized but does anyone know for sure? Montana doesn't post the specifications.

The hand out folders state Fresh water: 66 gal - Waste Water: 50 gal - Gray Water 93 gal. It is the same for all models of the Montana at least the 2011, 2012 and 2013 models.

I removed the underbelly to add additional support for the black and the gray tanks and both tanks and they are exactly the same size. The tank specifications for our 2008 are the same as the newer models.

Thanks Don, it is terrific to know someone has actually checked the size of the tanks.

I measured the side by side black and grey tanks and got the same size but did it from up top so was concerned I missed something that I could not see. It sure seems like the galley is smaller on mine. Good to know they are in fact the same size
