Storage cover for winter

I use mine, however it is important to keep the snow from accumulating on the bottom of the cover at the ground. Last season my cover got trapped into the snow / ice and as the ice shifted during the winter it pulled the cover down so tight that the trailer walls pulled downwards. As the walls were pulled downwards, both the roof and floor of the trailer bowed downward at the edges. In the early spring months, the vinyl floor was stretched around both sides the entire length of the trailer. The roof material was also stretched along both sides for the entire length of the trailer. Imagine a running line bubble of stretched material down both sides... I don't imagine it was good for the structure of the trailer.

This year I will shovel out beside the trailer during the winter.
