Was at the factory last week and they had their cover on display on a trailer and we decided to give one a try at half the price of a Calmark cover. It comes with a 3 year warranty so it may not last as long as the Calmark, but we'll see how it weathers. Have not put it on as yet but will post pics. when we do. One difference is that it has "Casita" on the front of it. Tim, in parts, showed me on the computer that it was made by Carver and their site listed it for $166.95 but with shipping from Washington, the cost would be close to Casita's at $289, so we brought one home. Going to polish the trailer it before installing it so it may be a while, the way I get around to things.
