The Truma is designed to fit in that same hole. The door needs to be installed perfectly though or you will see a paint edge.
What might be a better option, is we can provide a black paint Truma door. Then, no need to take it to a paint shop...and it would match the black door trim, black windows. We have done that before.
The biggest issue is getting the flow right, which can be done. I do know others have adjust the flow sensor, but that would void the warranty I'm guessing.
