Has anybody tried to add a gray water holding tank to the underside of their pup? I would love to be able to plumb my shower and sink into a mounted tank instead of having to carry a portable tank around. That would even give me the option of carrying the portable tank to drain the mounted tank when it gets full.
I found this one and I think it will fit reasonably well into the available space under my Flagstaff 625-D. I may have to move a pipe or two to accommodate it. I am a little worried that it will reduce my ground clearance, I was hoping for something closer to 6 inches deep. However, the majority of those are either tiny or too big for the available space. I think I could reasonably fit one as large as 21x32.
Does this even sound like a good idea, or is it a disaster waiting to happen? How difficult is a project like this?
