RV Window is Leaking from the top

[tlukasavige172]

I have a fifth wheel and the windows on both sides of the RV in the bedroom which is above the 5th wheel pin, are leaking. The leak is coming from the top of the window. I think the rain is running down the side of the RV and then running through the molding on the windows. I looked at the caulking and it looks to be in good shape. I also put some tape over the top of the window to isolate the problem and when the window is taped near the top there is not any rain that gets in.

So now I'm wondering what the fix is? Do I just need to replace all the rubber molding around the window? Is this molding specific for certain windows or does it come on a roll and you cut to fit? Thank you in advance for any advice.

Not overkill, you posted the correct fix. Anything else is a band-aid.

What type of DICOR are you using? It's a smooth aluminum sided RV, like a race trailer.

Get a tube of DICOR and reseal the tops of all the windows at the same time
Good Luck, Mike
