Brand new Kodiak trailer - can't use toilet

From what I can see in the pictures, they simply didn't cut a hole in the tank. I don't see the "there is 1" from the toilet flange (exit of toilet tube) and a protrusion on the black tank (a shelf above the drain valve)."

If that's right, a side cutting bit on a Dremel would fix it in a jiffy. Don't let the cutout piece fall into the tank, it might eventually block the drain.

What you are seeing in the pictures is the BOTTOM of the tank. Cut that and you have nothing. The tank has a shelf like a truck camper cabover with the exit valve underneath. Someone decided it was a good idea to install the toilet directly above so it drops onto this shelf.

Looks like the floor plan was all that mattered and functionality was ignored.
