2021 29G black water tanks

[bmcsbennett]

I have a 2021 Momentum 29G. I have 2 black tanks and 1 grey tank. Does anyone know what the capacity is for the 2 black tanks? Manufacturer said capacity is 56 gallons. Is that split between the two tanks?

From what I can tell in our 29G, yes. And note the kitchen sink drains to the rear black tank. And the rear black tank does not have a built in flush like the front. We never use the rear toilet for poo.
