That's my "unreasoned reasoning" as well. About the only accomplishment (other than eliminating one valve) is to equalize the weight distribution between the two gray water tanks. No matter the source of waste water (galley or bath) both tanks will essentially maintain the same weight as they fill. As I said in an earlier post, if the tanks are co-located, it may be a cheaper alternative, but it does limit the placement of tanks and wouldn't work on floorplans with the kitchen on one end of the trailer and the bath on the other end. There's no way to maintain a drain slope from the distant tank "inside the coroplast" and anything full of waste water that's run below the coroplast will freeze in a winter environment.

It looks like a good idea for some floorplans but not for all/most of what Keystone builds.
