Momentum 28G grey water tank sizes

[Tommyj]

I have a 2020 momentum 28g which has two grey water tanks, one for the kitchen sink and the other for the shower. Can anyone tell me the sizes of those tanks?

From the GD website they list 78 gallons of grey storage. This is usually divided into the 2 tanks, so 39 gallons each tank. It also lists the black tank at 39 gallons. You could call GD with your VIN and they will tell you the capacity.

They are about 35-38 gallons each.

You have three waste tanks in your 28G. They are all the same part number H1024 (Drawing attached). As Brian stated, the tanks are 39 gallons each. The leading tank is Gray, followed by black, and another gray.
