Finally found that leak

After several months of chasing a leak
In the roof of our 1992 excella, I finally discovered the place.
Along the way I have found a method for finding possible future leaks and, fwiw, thought I would share it.
After recaulking around the bedroom ceiling vent/fan and the waste tank vents, still had moisture running down the inner frame and soaking the floor along the side wall.
The only place I hadnít really considered a leak to be, was the riveted seamline along the roof that runs front to back of the trailer.
I wasnít excited about drilling out and replacing a plethora of rivets based on a guess, so I grabbed a small ball pein hammer and lightly tapped along the rivet line in the area in question.
What I found was water drops and bubbles coming from the joint line when I tapped the seam.
The leak was confirmed.
After removing 10-12 rivets and cleaning the seam, I recaulked the seam with trempro vulkem sealant and replaced the rivets.
After 2 down pours here in Oregon, the leak appears to be fixed!
The only disappointing revelation was the lack of original sealant in the rivet seam to begin with.
