Update:
Well, that wasn't so bad after al!
The weather today has been amazingly great for a change, so I figured I better take the bull by the horns and get to work on this awning before water finds it's way in there and makes a mess of everything.
I grabbed my drill with square #2 driver and climbed up the ladder. Removed the screw holding the vinyl strip end and pulled the strip out of it's track. Other than all the screw heads sticking up way higher than they should be, I noticed right away that two of the first ten screws were not there - never had been, no holes in the wall for them. I removed the ten loose screws and tried to test fit a tri-lock rivet. The rivets I purchased from McMaster-Carr are 3/16" diameter and the holes were just a tad too small. I got a 3/16" drill bit and carefully resized each hole in the aluminum track. I avoided cutting into the filon except for the holes that weren't there. At this point I opened my tube of Alpha Systems non-sag sealant and laid in a generous amount under the track. When I went to insert the first rivet I found it was still too tight to push in barehanded so I used a 1/4" deep socket and a small hammer to tap each one into place. Then I started setting the rivets, the track snugged up to the wall nicely and sealant was squishing out everywhere. I set all the rivets and then added a blob of sealant to the head of each rivet.
Moving on to the next screw I attempted to remove it using the driver bit and my fingers. That one and the next two came out easily. The fourth one was quite tight, as were the rest of them. I drilled out the track holes, shot a bunch of sealant into the holes and riveted them - sealing the tops.
I decided to not change out the remaining screws since they are all quite tight and there doesn't appear to be any problem. I reinstalled the vinyl cover and fastened the end. I'm currently waiting for the excess sealant to harden up enough to trim up with a blade. I'm quite happy that I was able to repair this awning track without leaving my camper at a dealership for six months!
I want to thank you guys for the guidance on this repair. I can say these rivets would never have entered my mind and I am sure anything else I might have tried would have ultimately failed.
