Had a similar cover on our last camper, think it was a Camco brand. It lasted about two years before the moisture destroyed the press board that holds the cover flat. It also held moisture in so that the tanks both rusted and there was corrosion/rust on the hardware and regulator. It looked nice while it lasted, but wish I had never put it on once I realized the dampness issue. The plastic cover on our new camper has much better air flow and access. The hard plastic covers now come in a shorter 20 pound size for about the same cost as the vinyl zipper covers plus they should last years longer.
