What can you do with the black water tank?

Uh.... can you sterilize one well enough that you'd want to put drinking water IN it? If so, help yourself, but don't EVER sell the unit without disclosing what the tank once held, or you'll open yourself to to a lawsuit ... and don't ever invite FRIENDS to camp with you if you want to keep them as friends.
You could use it as an extra gray tank. Most times when I boondock, it's a full gray tank that necessitates an interruption or end to the time off the hookups. It's a lot easier to carry in extra water than (collapsible water bladder) than to carry a blue boy or hook up and go to a dumpsite.
