How effective is a cover for a camper ,is it worth the trouble, I am in southern Michigan, not in the snow belt.

If you live where it freezes a lot in the winter, I am a pro cover guy. If water gets into even a tiny crack in the roof will let a couple of drops in, It will swell when it freezes. The water will melt (the next day if its sunny?), and a bit more will get into the crack. The process continues, the crack keeps getting bigger.

Granite boulders get cracked in half from this process in the north country over a period of years. Probably best to keep the water off the roof if you can do it.
