Britt, I am in the same situation. I don't winterize. If it looks like it may get below freezing I have 2 electric heaters in the coach and a small cube I put in the wet bay. If it is going to be really cold I leave the hot water heater on and the refrigerator. On my coach there is a heat wire that runs along the water line and solenoid for the ice maker. I found this out last February when it got down in the low teens. We got back in between storms and I made the mistake of shutting the refrigerator off. Later found the ice maker valve had cracked.
