The opening from the original fill wasn't big enough. This one is a little bigger. I had to use an oscillating tool to widen the opening. As you can see from my picture, my camper is a little older. Not sure if it will bolt right up to a newer camper/RV better.
Even with having to modify the hole a bit, it wasn't a bad replacement job. Added som butyl and some caulk to seal it up. Looks much better than my dry rotted, brittle original one.
