I'm doing a Cargo Conversion, and have 2 40 gallon tanks below, one grey, one black. The black will be directly below the toilet, with just a 3/4 ply floor separating the tank top and toilet floor. I'm using a standard RV toilet.
How does the toilet attach to a black tank? I see fittings that look like I cut a 3.5 inch hole, and they pop in place and get sealed... then what???? Can anyone provide links to what I need?
Thanks all!
