1. Walker assemble pre-packed items that fit several models of awning - a throw back to the company they took over. Place to one side and forget all about it.
2. You can either separate the two parts of the stud fixing the back part to the van by gluing in the appropriate place or, alternatively, as I have, purchase some sticky pads (velcro on one side, sticky on the other) sticking one part to the van and the other to the skirt. What I have done is buy the velcro/sticky pad stuff, cut two squares approx 3" x 3" sticking one piece on the skirt over the studs and the other part in the appropriate position on the van. The velcro sides must come together obviously.
3. That plastic runner fits on top of the vans awning rail as acts as an extension/hightening piece to the said rail. In effect it hightens the rain gutter. (see attached image).White Strip.jpg - Bild entfernt (keine Rechte)
