I use the CASSETTE POTTY and it doesn't take muc room. This has a 6-gallon pull out black water tote tank on wheels...
My POPUP trailer has the full version of this with the shower combo but for us that was a waste of room... We end up washing up at the sink...
You won't need all of the expense of adding the black tank and plumbing for this setup...
With this setup you can add the top wood piece and store things on top of it until you need to use it...
I just pull this tote out which has two wheels on it and go dump it down the toilet at the camp ground...
