If you have physical access to the tanks, and if they are square sided then it's fairly easy...
I had to do this with my old coach...
I'll use my fresh water tank as an example...
The tape measure says the outside dimensions are 22.5 inches wide by 15.5 inches high by 44.5 inches deep
22.5 times 15.5 times 44.5 is 15519.375 cubic inches
15519 divided by 231 (the number of cubic inches in a gallon) = 67.18
but we are using outside dimensions for simplicity and that ignores the thickness of the tank walls... so call it around 66 gallons.
A while later I found a brochure from the vintage of the coach and it said 65 gallons. Close enough.
