Query: 18-by-24 Silver/Brown only lasted 20 months in the shade

I ordered two of these for a car tent. They are not as heavy duty as the White CANOPES I got from Orchard Supply Hardware.OSH brand lasted about 6 years. These lasted 20 months and are noticably thinner/lighter weight.I overlapped these silver/brown in the middle of my 35 foot run with the brown facing out/on top.One was in the sun for a few hours a day and has split 12 feet long at the middle where they glue panels together.It worked well until now. Made it by two winters but just 1.5 summers.Seemed to shrink a bit and have too much stress on the lap joint and pulled it apart.I will try looser bungie cords next time.Still the same price as back in Nov 2008.
