Grey Tank

I just purchased a 2012 Montana 3400rl Hickory edition and was wondering about the size of the grey water waste tanks. The specs list 93 gallons grey tank capacity and 50 gallons black water. I have 2 grey tanks, is the 93 gallons total capacity for both?

Just divide by two. Hopefully they told you the other dump is probably along the frame by one of the tires on the street side. Also, welcome to the forum!
