Abstract
Abstract A boot for a cab-and-camper recreational vehicle is arranged to facilitate installation. The boot includes a sleeve for defining an air corridor in the spacing between facing open windows of the cab and the camper. A first frame has one end of the sleeve substantially permanently secured to it and is installed in abutting relationship with one of the windows on its interior facing side. A second frame is installed in abutting relationship with the other window on its interior facing side. The sleeve, during installation, is pulled taut and its free end is fastened to the second frame so that the sleeve, being in tension, exerts a pull on each frame thereby holding them flush against the respective windows.
