why separate tanks for grey and black water?
Hi Folks, Let's say I'm building my own RV. Is there a reason I can't use the same tank for grey and black water? -Tom

For a home builder handling and installing a 50 gallon grey tank and a 25 gallon black tank should be easier than one 75 gallon tank.
In my experience, and talking to literally hundreds of folks, several dozen full-timers - the combined capacity of the waste tank(s) need to be at least five to ten gallons over the capacity of the fresh water tank.
Most people I've met will have to empty the grey tank twice, sometimes three times, before they need to empty the black tank. Even folks who use plenty of water to flush the toilet.
(Of course we aren't boondockers who are careful about every once of water they put in the tanks.)
Most of us do things like leave the water running to brush our teeth, rinse dishes, etc. Which puts more water into the grey tank, certainly more than we should.
