To pump from one tank to the other if you have two separate dump valves for the grey tanks, you could get by using a 12v water pump but a macerator pump might be better. The macerator pump would break up any small solids (hair, sand, gunk...etc) that might come from the shower.
You can get caps with garden hose attachment bibs, connect a garden hose between the two dump valves. Cut the hose and tie in the macerator/water pump to pump from one to the other. The macerator pump would also provide the ability to pump out all of your tanks to something other than a dump station (like a sewer clean out connection) if needed.
