I saw this on a recent campout. Guy had taken some 1 inch PVC pipe and a couple of tees and fabled a length of pipe with feet, using the tees, which he added to top of slide out. His issue was the awning was developing water pockets, he ran the awning out, then the slide, then added the length of pipe to support the awning upward to hold it off the slide out and remove any pockets for water to pond in.
