Covered my 30' travel trailer outside. Deteriorated after 11 months, one summer in Fla sun. Tore along seem lines, high side and low side, and material just turned to dry, almost powdery mesh. ADCO would not cover.Fine product if you're covering something inside an air-conditioned space. Now of course, um. why would YOU BUY A COVER IF IT'S MEANT FOR ONLY INDOORS?!?!Waste of money. A lot of money.See full review
