We have 3 toppers on our 3 slides. Since we were spending winter in windy VA, we bought 3 Air Wedges and one blew out within the month. Other 2 didn't fare much better. But I least I saw the 2nd one blow out and made DH run out and grab it before it flew away. LOL
They are now packed away in our basement.
