  Does anyone here recycle grey water? Especially when boondocking like say for toilet water flushing?

I know this is an old post, but I've always wondered the same thing! It seems like it would make sense but would require an additional pump and plumbing.
However, our current coach only has one waste tank, so its not even an option for us.
I imagine crud in the gray water could clog up the little parts inside the toilet, but thats purely speculation.
