If they go to the same dump fitting the solution is VERY VERY easy. buy a twist on gate valve. When one tank gets full, install the twist on gate valve to the dump tube, CLOSE the twist on gate valve, OPEN the two grey tank dump valves. Water will equalize between the two tanks.
you can then either leave the twist on valve on till you empty or close the main gate valve and drain the gallon or so of grey water from the line into a bucket by opening the twist on gate valve.
We also have two 32 gallon grey tanks, one in the galley, one in the bathroom. We use this trick. AND when you dump, use the gate valve as well. empty the black tank first, then close the twist on gate valve, Open one of the grey tank valves to backflush into the black tank, close the grey tank valve, and open the twist on gate valve to flush the black tank again. repeat as needed.
