We had a similar leak that I thought came from the passenger side upper bunk window. I sealed the window and that didn't work and after further inspection I found what looked to be some hairline cracks in the sealer at the curve on the roof. I talked to our dealer and he did say that was an area that needs to be watched and recommended a self leveling caulk. So we cleaned the area and applied the caulk and it stopped the leaking. The corner of the roof that meets the front cap is where I thing the problem was and if the RV is sitting tilting forward it does puddle in those corners. Hope that's not to confusing.
