I compared mine to Lou's and find that his is of a better design. I guess mine is the way it is because it comes with a screen door (I have the frame and need to rescreen it).
it appears mine did not have a door rubber gasket when new. I see a foam one glued into the casing. Lou's casing has a channel that his door fits into nicely when it is closed that mine does not have. I got used to the wind as it drowned out the daggum beeping the Norcold was making because the doors were being jostled. (my first mod to the coach will be to remove that beeper from the circuit board before I leave IN). The door is slightly askew but tight onto the hinges and I have not figured out how to adjust it yet.
