I had the same problem with my other Montana and to fix the problem I did what was talked about above. Put foam around the water lines that are laying against the steel frame. For the low point drains I did something different. I added a shut off valve to the bottom of each tube. Then in the fall I would drain everything. After that I would take a large syringe and fill those tubes with the pink stuff and shut off the valve. Being these are low point drains there is no place for the pink stuff to go, so it remains in them and thus no more freezing.
