Aluminum walls are cold!

We just camped for the first time in our new to us 2005 Airstream Interstate.

It was in the low 40's at night, and we did have the heater on appropriately.

But boy, those walls beside the bed are really cold! COLD!



I would love to hear what some of you have done to combat those cold walls. You just can't help but touch them somethings during the night.



Thanks!
