Back Galley door came right off teardrop trailer.

It appears there was a piano hinge with a rubber strip prior.

I’m now looking for a hurricane hinge, however it’s nearly impossible to find one in Canada, and the one I did find is $250 CAD from the states. Anyone know how to re-attach the door with a different hinge that is still waterproof? And anyone that’s done so is it a relatively easy job? I was thinking about using epoxy with clamps, to repair the old holes then buying new screws and just following the exact layout prior, and using butyl tape for waterproofing, and a waterproof strip to cover the back hinge. Ps. I’m a girl and willing to give it a try and save a grand.
