hinge is a rare beast. They used a commercial refrigerator
hinge made by a company called Kason. Kason is still in business but their model No. 139 with a 3/8" offset is tough to find. I found a spare set at McMaster Carr, part no. 1276A52. They might have them? Trillium
Outback in Canada has them. Trilliumrv lists them as well. One member found a set with zero off set on ebay and added a spacer. Unfortunately anything found at the hardware store will require a lot of improvising.
Measure between the upper and lower screws. They all should be the same. If not, your door may need resetting. Many were screwed into a piece of wood in the wall of the trailer that rots over time.
