It would be fine in an enclosed trailer. We have only been getting snow storm about one day a week, and it is usually only a couple inches. It has been in the 20's here, but that doesn't matter much for hauling the car. I guess as long as you aren't hauling on a day it snows, you'll be fine. And if it is snowing, just drive slower. Just do it now, you can have fun with it sooner then.
