Thanks everyone for the advice and the suggestions. I received two responses from kijiji.ca locally and just installed a replacement today.
My first call was from a rural pastor who had purchased a mid 1970's Kustom Koach to use for storage. He removed the fridge last fall
and put it in a storage shed. He plugged it in and used it for extra refreshments this spring, but decided that he needed the space, so listed it for free. It wasn't an exact fit, but was 6" too tall. I brought it home anyway and plugged it into 110v and it immediately froze a cup of water.
My second response was from a person in my own neighborhood who had a large tree limb crush his 26' trailer last fall
. He allowed us to come look at it, and he tested it overnight for us and it worked well. This is the one we installed today. We are now happy campers (literally)
