I have seen lose rivits that retain mounts on my trailer and just passed that off as stress from wind resistance when towing (TV antenna mount). Same can be said about the awning rail with the awning deployed, wind flapping the fabric over time would put great stress on the rivits that attach the rail to the skin. These will leak over time. If you read some of the posts on axels you see alot of people are replacing axels because of the rough ride on the trailer while towing. It's not to far off to imagine that some of this towing stress is passed to the joints in the skins and can lead to rivit failure and leakage. I have been on the hunt for leaks myself, most of mine is the rear bumper mounts alowing rain to pass under the skin to the wood subfloor. I have yet to see a roof leak but will do the wood popsickle stick method and remove then replace my sealant.
40 years is a long time for this stuff to hold up.
