It is hard to believe a 2 year old refer is obsolete and parts are no longer available. There may be a RV junkyard near you where a door could be found?
This has happened before and, as I recall, you are going to be disappointed in your repair options. I remember people repairing/manufacturing the door bracket to fix the problem. Do a Search here with keywords like refrig hinge broken repair etc. and you should be able to find it.
I did a bunch of Searches with different keywords. I remember someone repaired the door and posted pictures. It was a long time ago but the idea should still work. Here is a post about RonD's repair of his door. It doesn't have pictures but it is pretty detailed with what he did. I happen to know him and that door repair lasted a long time until he traded the Montana and went to the dark side.
