Oh yeah, it disintegrates very quickly. The dealer replaced mine with a Fantastic fan vent under warranty & threw in a Maxair II cover to boot. It had cracked while on the lot and leaked before I purchased the camper. It is in for more warranty work now, one item is replacing the bathroom counter because it was swollen from the leak.
