^ This.

One suggestion: if the outage is going to continue indefinitely and for whatever reason more propane can't be delivered, the propane tank contents can last quite a bit longer if the generator is turned off periodically; e.g., for a few hours at night. We got through a 12-day outage that way, and the contents of our two refrigerators held up surprisingly well.

It was only after 6 days that it became clear that we would eventually run out of propane before a delivery could be made again, so I don't have a clear idea on how long refrigerator contents can last when they're turned off for ~6 hours each night while the doors are kept closed.
