8528RKWS galley tank capacity

The specs on the gray water tank show 76 gallons for that tank, but does not show a separate capacity for the galley tank.

Is the 76 gallons a combined capacity of the two tanks? If so, what is the size of each tank?

I believe it will be 38 gallons each for a total of 76.

Rockwood told me if the kitchen sink is too far from the bathroom and the drain pipe drop won't be steep enough they add a galley tank.
You will probably have a separate dump connection for the galley but there are a number of threads where people plumbed them together like this.

Only one way to verify. Measure and pour. Some RV owners have said (here) their tank only holds 1/2 of what was on paper.
