[A/S] how big is your gray water tank?

["burnsmontyc" <burnsmontyc@xxxxxxxxx>]

My '57 Overlander has gray water plumbing, but will only hold a few 
gallons. 

I wondering how many gallons of gray water two people make per day?

I an thinking of buying one of those mobile 36 gallon plastic carts 
that you hook up under the trailer, and then empt in the dumping 
station.

The Black water tank is fine.

any thought?
