Window leaks--front and rear?

[Kistler]

We were in a lot of rain in The South in April and the front (above the couch) and rear (above the night stand) windows leaked. The water collected in the channels in both cases and seemed to come from the top.....small drips....but after 12 hours would fill the channels and in both cases they seem to slope inward so especially in the bedroom above Brenda's bed (we're always leaning that way no matter how hard I try to level the thing) it soaked the wall a little.

I caulked all those little center-of-the-rivet holes in the front and that seemed to almost fix that perfectly but the bedroom isn't made the same--no little rivets with holes--think the front has them because of the rock guard.....

The rear leaked less if I unlatched the window--I have rimless windows and the window is locked with sort of twist and snap type fasteners that are adjustable. Do you think it is possible that the window cinches down to tightly--fasteners are at the bottom--and somehow a gap is left at the top because the bottom is so tight??

Where else could the leak(s) come from. Everything looks caulked--clearance lights, seams, etc.

My rear leak was coming from higher up....yep....the rooftop vent cap vulkem had become unbonded and was allowing seapage into the inner wall, which was running down the interior frame structure and then down into the coach, and it only appeared that the water was coming from the window, or the rear running lights, or tail lights.
Leaks are a difficult thing to find at times....good luck.
