This is just an extra.  It comes in super handy for our composting toilet and we suggest picking one up if you are considering a Natures Head composting toilet. You can purchase from Amazon here http://amzn.to/2witEGF but it's more expensive than buying direct from Nature's Head.

A composting toilet has been one of the best Wild Camping mods we have made to our RV.  A composting toilet doesn’t use any water, its environmentally friendly and we don’t have to worry about a stinkin’ RV black tank!  Sound too good to be true?  It’s not, you can see all of our composting toilet info and videos here: Composting Toilets
