We've got an Outdoor Revolution air awning (Esprit Pro 420), which we have had for three years now (which is our whole caravan owning time... we're relative newbies). I've never really been happy with the awning. It's very heavy to feed through the awning rail, and it doesn't seem to "sit well" on the side of the caravan, if that makes sense. It is impossible to get the roof nice and taught, and it generally looks quite saggy and sorry for itself! Also, suffers terribly from pooling of water on the roof and from condensation. Judging by some of the posts on CT, these problems are not uncommon
