Received my new skymaxx hatch. I have installed the parts from the new one to the skymaxx on my Host. Fourteen months to finally get it fixed. Pins on the bar handle that hold it open or locked closed and broken hinges on the handle assembly. I jury rigged it closed with bungee cords. It was really disheartening for us to have our new camper with this defect and to have to deal with it so long. Skymaxx will not sell parts to anyone, only the whole assembly. I wanted no parts of disturbing the roof seal on our new camper to replace with a new skymaxx. Artic Tern looks like a nice replacement. If anyone is purchasing a new host, please do not get the the skymaxx hatch. It is cheaply made and parts cannot be purchased. Thanks for letting me vent and I hope I've helped someone. Barry
