I just bought a Dometic 320 porcelain toilet to replace the plastic Dometic in my new travel trailer.

I am having trouble getting the base to sit level on the floor. when comparing the 2 bases they look exactly alike. If I remove the rubber gasket then it sits flush on the floor, I even tried swapping gaskets thinking that would do the trick.

The base is tightened down to the ring as tight as it will go without popping the bolts through the ring.

Has anyone else had this problem or have any suggestions?
