Gray & black tanks

Our Montana 3910 has 2 grey and 2 black tanks. Specs say 93 gal for grey & black tank each. Would it be safe to say they are divided equally among the 4 tanks and also because they are smaller could just possibly be more durable.
Also the fresh water tank is clear at the back. 66 gal that far back could not be good, full , going down the road but then most of us carry very little fresh in our tank.
Oh and by the way it is one sweet coach.

Close. 93 gray seems to be the standard for all floorplans, but believe the gray tank for the bathrooms are a bit bigger; we have always found the kitchen tank to fill up faster. 50 is the standard for the black tank, so would make the assumption one standard 50 gallon tank, and a 43 gallon tank for the other bathroom. Would not make the assumption they are smaller except for the second black tank. Would think three of the four tanks are the standard ones installed in all floorplans.

I don't think you have something unusual with the fresh tank all the way in the back. Ours is that way and every factory tour I've been on, that's where they were putting the one they had on display.
