Camping in the cold weather can certainly be a challenge. Chances are, there is just a small duct providing limited heat to your underbelly. Without a barrier around the outside perimeter of your unit to block the wind, its doubtful you'll be able to prevent the water from freezing. I'm sure others will chime in with possible tips for you to consider. For me, cold weather camping isn't a very pleasant experience.
