I would like to know what the sizes of the black water and the gray water tank are in gallons. Anyone have any idea?

There are roughly 7.5 gal in a cubic ft. If you know the dimensions of your tank you can calculate the size of the tank in cubic feet and convert it to gallons by dividing by 7.5. If you calculate the volume ot the tank in cubic inches divide by 12,960 to get the size in gallons.
