Those that store their campers..when you pulling them out!

I've twice made the mistake of working hard to winterize my unit only to pull it out too early in March and have a freeze break something. Granted, it's just a trailer so it's not like a house pipe crack.

Still, Central Indiana can be very far below 32 well into April. These are really just big toys, you have to follow the rules if you want to keep them nice.
