I also have an awning question. When closing the awning, one of the black knobs was loosened a little to much and fell off along with the nut that it screws into. How much of a problem do I have here? Appears that it screws through 2 c channel type metal bars. They are inside a larger c channel type bar that has solid back and it looks like I might have a big problem getting the nut back into place to screw the black knob into. Major problem or am I just over thinking this? Didn't try to open it yet to try and fix it. Manual awning that appears to be the original awning. It's a 2005 so hard to say for sure.
