Banana wrap and C channel overlap?

I am getting ready to put the wraps back on but got to wondering about how they attach at the top. The original wraps were riveted along the same line as the bottom of the outer skins over lapping them. This almost guaranties that water running down the side of the trailer will go inside the belly.?? This just seems wrong to me. I noticed that the C channel has a step in it and looks like the banana wraps could (should??) be fastened in that step. this would help keep water out of the belly but would require rivet holes into the c channel right into the ends of the plywood floor (also not a good plan). So what are folks doing about this? I thought I read a thread on it a long time ago but now I cannot find it.

Any Thoughts??

It is best to put the wraps under the outer skin but it does not always work out that way. I ended up sealing that joint with Trempro-635. It is also important to seal the top edge of the trim once you rivet it back on. As long at you seal that joint inside and out it should not matter. If you are completely rebuilding a trailer and you can pull everything loose and put it back with the proper overlap then do so but don't loose sleep over it. Most of the time there are rivets in the way that you prevent you from getting the wraps skins under the outer skins.
