Tyvek versus PolyPro Covers

[2dreamers]

Does anyone have any experience/comments regarding the relative merits of the 3-Layer Tyvek Designer Series (Adco) cover and the PolyPro lll Deluxe (Classic) cover. We want to protect a Class C (with rubber roof) from typical central Canada winter conditions - rain, ice and snow. The information supplied on the companies' websites suggest either one would work well in the conditions we have, but we are also looking for a cover that has some longevity. Thanks.

I have used both. The Tyvek one is really only Tyvek on the top, with heavy polysides. It also has access zippers. Works well, but pricey.

The poly is only poly - top and bottom, and seems thinner all around.
It's less expensive, I believe.

Both seem to last about two years in the elements. For heavy duty use, the Tyvek has the edge.
