Cold... shrink... stiff... So many possible jokes here...
We camp in 5 degrees F or colder all the time. Once the heater gets going, things usually loosen up.
My classmate from Alaska had -70 F once. No propane at all, and all the fiberglass on the shell of his class C cracked while going over the bumps!

I don't know when we'll be able to go camping again...
