refrigerator in cold weather

So much paranoia. My old 2807 Dometic works flawlessly at -7°F with NO mods. Think about it, the refrigerant in the system gets way below 0°F when it passes through the coils in the freezer, even in the summer. If it's cold enough out side to change the state of the refrigerant in the system, you won't want to be there. I did add a 4" fan to the outside to assist cooling in extreme heat.
