The repairman is likely correct because if your temperatures in the cabin get down below freezing that will cause the compressor to stall and fail. The compressor would need to be replaced again if that is possible on an unit this old, and you would either need to shut the refrigerator down if you're going to be gone and it gets that cold inside the cabin, or you'll need to heat the cabin enough that it doesn't get below freezing inside.
