In those warm temperatures you have nothing to concern yourself with. NOTHING!!
When the temps get down to below minus 10F, I start to take notice.
If it drops a bit more, then I stick a light bulb in my fridge compartment to warm it up a bit.
I have lived in my RV in temps below -25C and no issues. It is when I get to -30C that the fridge sometimes will falter a bit. Couple months ago at -34C my fridge started to freeze up. I stuck a light bulb in the compartment and it resumed normal operation.
Currently minus 24C here (-11F) Fridge is working fine. It is supposed to get a little cold tonight so I may go put my light bulb in the fridge compartment. Yeah, guess I should do that.
Wind chill is expected to be -42C tonight (-43F) yeah, suppose I should pay attention....
Really though, in the temperatures you mention, you have nothing to worry about and don't need to do anything. Your fridge will work fine.
