Idea musing. How to modify a small (dorm/hotel) fridge stay cold for days unpowered or extremely low power?

This topic comes up in RV forums often where propane fridges are common but getting replaced with home units. Could you take a small dorm fridge and add a very large reservior to it to get it to stay cool for -- say 3-5 days without needing to run the compressor? What would you need and how much of a reservoir would you be looking at? Converting a system like that to a 15 pound refrigerant grade propane is tempting too. Or would this need a rediculous ammount? How would you accomplish the same task in the industry?
