Truck Camper Cover needed, Recommendations?

Based on most of what I read here about covers, sun is the biggest enemy, yes? My camper will only be outside during the winter here in the Pacific Northwest, and won't be exposed to much sun. It'll be stored indoors in the summer. In this case, should I expect a better life-span from adco or Classic Accessories? I could easily see the Calmark cover being worth the price of admission if I was in a sunny area and storing outdoors during the summer.

I'm also considering rigging up a tarp on a roller with 2 poles attached to the roller so 2 people could deploy it and store it in a matter of minutes. Anyone ever seen something like that?
