I put my gizmos on from inside the bunk. I asked Bob from PopUp Gizmos to sew a strip of Velcro onto the top edge of mine. I placed strips of Velcro on the top inside of the bunk door frame, and after opening the bunk door I climb onto the bed and pull the canvas over my head so that I can access the top of the door frame to attach the Velcro. This insures that wind and water does not get between the gizmos and the canvas from the top edge. I have a 2012 21ss so the canvas is not permanently attached to my bunk doors. This method would not work on the newer models where the canvas is attached.
