We live in the Chicago area and it will soon be very, very cold. Our Class A RV sits in our driveway and we will take it to Florida in January. I am wondering if we should winterize it for the few months it will be here in the cold weather? Then, we will take it south and flush it out and it just seems like such a waste but we sure don't want to take the chance of busted pipes! Any ideas?? Thanks so much.
