We have a 2021 GD Imagine 2600RB. The owner's manual was updated 7/2020. There are no references to individual grey tank sizes. I've read through the entire manual. The plumbing section does not have a tank diagram.
According to the parts listing on the GD website:

Fresh tank is 49 gallons
Black tank is 44.9 gallons
Each grey tank is 36.45 gallons
