I know the cold weather guys will chime in but just from a logical standpoint could you perhaps wrap it and store it in a highly insulated container of some sort? Just figure out something with multiple layers of material to shield it from direct cold? It seems like given enough time cold will find its way in to any system, but if you pack it in a multilayer system of insulating materials and an airtight container or two, be creative, it will keep cold air away and protect it??
It doesn't sound ideal but there must be a way.
Yes, Gregg is quick to reply, ask him.
