Corner Leak Round 2. Bill Marshall & I had a good email exchange about this continuing problem and think we may an explanation if not permanent solution.  As many A-Framers know there seems to be an ongoing problem with rainwater leaks, particularly in the corners where it puddles up and may cause floor rotting problems.  I thought I had it solved in my previous modification on this topic but alas I still see signs of moisture in my storage compartments.

In case you don't want to read the email thread, the culprit is that rubber seal that runs across the rear roof section about 3/4 of the way up (seals the front section when closed).  As Bill observed this acts as a "gutter" to channel rainwater across the roof, which doesn't pour off the ends as expected but rather follows the inside of roof edge down to the corners.  I believe this is caused by water's properties of cohesion, adhesion, & surface tension, so if you add some means to divert it off the roof before it can perform this little trick the problem is resolved!

Bill made some diverters to test his theory and I'm trying some plastic spouts I picked up from CW.  We have trip planned for the Oregon coast in late July and since there's always a chance for rain there year-round I may get to test mine in real world conditions.  Stay tuned!

There are some pictures in the thread which illustrates Bill's test & my solution.
