The Outdoor Revolution type awning has stitched in thick foam pads that lie against the camper sides.
I have two Houdini type escape artists (Bichons) who will find their way through the smallest gap, so to prevent this and keep any draughts out, I stuck 2" wide white Velcro down the side of the FC on the metal body and stitched onto the awning skirt. I then stitched the same to the Porch Awning. That sealed the bottom section.
I then made up two strips of duck tape, fastened front to front with super magnets sandwiched between the two layers. I then stitched super magnets onto the Porch Awning to line up with the ones on the tape.
With the awning erected and the Velcro stuck, I placed the two taped magnetic tapes down the inside of the canvas and plastic window and this held the rest of the awning wall firmly against the canvas side of the FC without any damage being caused to the fabric either on the FC or the awning.
It was goodbye any draughts and one of my more successful modifications!
