Newer Burros have a Hidden Hinge system. It works so well that even I can't find them
Actually, you can see them, but the door needs to be open to do so. They are on the inside and swing out from the coach at the door frame instead of from the body.
Don't really think it's too secure. Before I had them fixed so the door didn't sag, I used a crow bar to straighten the gap when it wouldn't open. All I had to do was apply a little more force and it probably would have ripped from the door frame and fell off.
My 13 had a floppy handle sometimes. This happened when the door was not closed properly and the dubiculous that went into the strike plate opening was not seated. The door mechanism was locked, but not fully seated. Have you checked that?
