About 10 years ago I bought an expensive cover for a Class A motorhome we owned at the time.
I was surprised to find out that it did not repel water. Water would run off under the cover just as if there was nothing on it. From what I understand most covers are water "resistant" and need to be so that they are breathable to avoid mildew, etc but my main objective was to keep the RV dry.
In our climate, especially now, our winters seem to be a constant freeze/thaw cycle and my suspicion is that the continuous expansion and contraction when moisture freezes/thaws in little cracks and crevices will eventually lead to trouble.
