Still makes no sense at all...I am from Manitoba...winters can be brutal on the prairies. Here ground freezes in Nov and remains so till April...we get colder for longer spells than Que...yes the ground freezes and shifts, but it's gradual, and if the ground does rise as you say the whole trailer will move slooooowly with it. It won't cause flexing to the point of breaking a window. Heck if that were the case, then how could any windows in our vehicles, homes survive. The earth heaves in winter, but your trailer is on a chassis sitting on rubber tires, it will flex. If that reasoning were true, then every time you hit a bump on the road or drive on uneven ground windows would break. If you drive down a road and things inside your trailer move around and the road is a bit rough, and windows aren't breaking...then frozen ground is not going to cause windows to break.
About 80 trailers where I store ours for the winter, plus 100's on the local dealer lots all winter, and we don't see broken windows all over the place because of the freezing weather/frozen ground...same thing all over MN, ND that have the same weather we do.
