Unpowered Freezer Temperature Fluctuations

If I store stuff in an unplugged freezer at "room temperature" in a vehicle what will the temperature fluctuations be in the freezer?


Seems to be silly, but I have excercise resistance bands and don't want to take them with me on vacation and would rather leave them in my semitruck (which will sit under hot Houston sun for a week). I was thinking of storing them in my mini-fridge freezer, but obviously I can't have the freezer on for a week as it'd drain the semitruck battery.


The temperature outside will fluctuate between 75⁰F-95⁰F everyday. That means the temperature inside the truck cab will fluctuate between 95⁰F-115⁰F everyday. But, what will the temperature fluctuations in an unpowered freezer be?

 

Dang, I don't have the time for freezing water bottles.

 

I supposed that.

 

Anyway, I saw that I had enough luggage room to take the bands with me.

So, case closed.
