Thought I was in a club by myself. MY Norcold lower door hinge broke off from the door,cheap plastic. I repaired it by making hinge out of
11/2" x 24" x 1/8" aluminum flat stock. Used the broken end as a pattern for shape and hole placement. Then cut total length to about
14" and the width to the width of the bottom of the door. Sheet metal
screwed the new hinge to the bottom of door and set it on the door peg ( used a couple of small washers on peg for height adjustment). Many happy miles later and still working fine.
