Rich,
If it gets cold enough (this is from personal experience), you will need to OPEN all doors that might be hiding freezables.
One year when we ran out of here, I put some pure olive oil in the back cabinet, it was liquid when I loaded it. By the end of the first day (we did not run with heat on that year), the olive oil was cloudy, and rather frozen. It thawed, no biggie, no damage done.
Point is, that it can get real cold behind those doors and stuff will freeze or come close even IF you have heat on in the unit. We will prop open the doors on nights when it gets down around 25 or below and we are in Tana, usually the first few nights outa here on our run for the warmth, err, Texas.
But you knew all this!
As for us, our freezables are stacked in the garage, where we monitor the temps, and if the temp in there gets below 30 we add a little (electric) heat for the minimum of time. If it gets downright bitter (like 15 and downwards from there), we will have to pick it all up and cart it into the house.
We are hoping for warm temps till January 5th, and we hope to be long gone by then!
