Will NOT last is right, bought first Adco cover and ripped apart within 7months. Adco told me that the one I had was a basic indoor dust cover so they warranted me up for $50 to this Gray one with the white top, ANOTHER piece of crap. It came apart within a year as well, I called them back and they say this one had no warrantee because it was a replacement for warrantee. Now they want to sell me another outdoor one for close to $400. I will not be a sucker again. will never buy Adco RV cover again.
