Just got a new catalog from these folks and they have what looks like a really good deal on a nice size enclosure. Based on what I read it sounds like they have a good product and a good warranty (15 years) on the material that they use for the cover. My question is this, Has anybody had any real experience with their enclosures/buildings and if so what do you think about their stuff? Reason I ask I want to close in my back shed for more "inside" space and they have a really good price on an enclosure, with one closed end and one zipperend end, that is about the size I need to store the stuff currently in my way. Any input would be greatly appreciated.
