tonneau covers
 

For those of you who have soft covers, how long do they usually withstand the elements (sun, snow, ice, etc)? Any brands people would recommend or warn against?

I had an Extang on my 2000 Dodge Dakota from early 2001 until I traded the truck in October 2008. It was still in fine shape with no holes or cracks. It was a snap on type and all snaps were still fine. I bought an Extang Trifecta for my '08 F150.

DO NOT use silicone based "conditioners" (i.e. Armorall). I only used Aero 303 once or twice in the 8.5 years I had the cover. Just for info I live in western Pennsylvania so I see reasonably sunny summers and have snow and ice in the winter. I am sure, however, that intense sun like in AZ or something would cause it to last for a lot less time.
