Grey Tanks Size

[jswharton]

Just a quick question, what size are the 2 grey tanks on a 2013 Montana 3100RL? There are 93 gallons of total grey tank capacity.

Thanks

I believe each tank holds about 38 gallons. for some reason they have the galley and bath gray the same size. at least that is what is in our 2005

The tanks were enlarged recently (three years ago?) but I think they both would still be the same size. Guess that would make them a little more than 46 gallons. Black tank is 50 according to specs. I would not think they would be different sizes since that would allow the "Amish Craftsmen" to get them confused and installed backwards, but knowing past practices........
Bingo

We have a 2012 3100RL and the Gray tanks are approx. 45 gal. each, give or take a gallon or 2. You are safe dividing the total in half to get the cap. of each.

X2, ours are the same size.
