Steve, I do understand the plumbing configuration on the single tank system.....Todd has that system on his '84, and I became intimately familiar with it the five days I was in Sioux Falls helping him get his coach ready for travel. If you are hooked up to a sewer the option to dump the gray directly into the sewer, bypassing the tank, is great, but we do a lot of dry camping, and once the gray water is in the single tank that's were it must stay until hooked up to a sewer line again....I can't just water someone's lawn, or run a hose into the forest with my gray/black water like I do now with the gray only. I believe very strongly that having two separate tanks gives me, personally, much more flexibility in the type of travel style we prefer, and utilize much of the time. We don't have to conserve on how much gray water we generate because we know we can get rid of it pretty easily.

If your style is to be connected to a sewer most, if not all the time then the single tank is the way to go. That's not my style.
