Wouldn't it be better to dilute the black tank with the nice soapy grey water?
Besides whether you can dump grey or not if you had only one tank you would have over 1500 lbs ( 8 lbs a gallon more or less) in one tank the tack would have to be heavier and secured better. That is alot of weight at one point. If you were going down round it would be alot of weight lashing around
