I have just spent the better part of two hours searching for something I figured would be a simple find --- replacement sleeper-boot material; comes in a roll and sold by the foot. I can find that accordian stuff everywhere, but not the big truck stuff, which is simply flat, with no edge-clips nor pleats. My sleeper is a Double Eagle; I tried my links to their site and only get "this site no longer available", like maybe they are no longer in existence. I figured I could have found this stuff, had it bought, and already been in bed by now. Does anyone know of an online source for sleeper boot material ?? I have found a few places that advertise replacing sleeper boots, but their sites are very spartan and only say that they do the service. Thanks.
