I grew up living in mobile homes in the Midwest. We endured some very severe winters with brutal below zero temps and survived. You can make most of these trailers capable of making it through the winter with some planning and some effort. Mobile homes of the 60s and 70s were not what they are today and it was a constant struggle to not have frozen water or sewer lines. We often had to leave cabinets open and faucets running in an effort to prevent freezing. The wind would blow and so would the curtains... it wasn't always easy.. but it was every day life!!!

The fact they sit off the ground means they will always be susceptible to freezing temps!!!

Without a doubt the polar package on my keystone is better today than what we had on the bottom of our mobile home in the early 70s.
