It could be worse. It could be raining.
aside, do you have a catalytic heater in your trailer? If not, it might be a good idea to consider my redneck furnace, which consists of a clay flowerpot turned upside down on one of the stove burners. Turn the burner on low, and it will help keep the trailer warm. Crack a vent or window so the stove doesn't gas you. Keep the main door unlocked, if you get an ice storm it could freeze the lock, and you'll be locked out.
