I have used my auto cover as a winter cover in pittsburgh for 6 years and just replaced the material. It does fine with the weight of the snow. One thing to wacth out for is that when you leave the pump on the cover over the winter to pump out water which you should do, sometimes as the snow melts the pump will run but the pump hose is frozen solid so no water comes outwhich can burn out your pump. A sparehose kept inside will help to fixthis
