I wonder if a person just changed the shape of the weep holes with some artfully applied black RTV sealant, then it would change the whistler, leaving it open enough to drain well??

I believe the key is reducing the size of the hole by tape, RTV, or the little plastic caps made by the window manufacturer just for that purpose.

If you tape over the weep slots you will have water enter your sliding window.

My Suncruiser came from the factory with covers over the weep holes. The covers are open in the rear so water can drain.

My first coach (1978) had the same weep hole design as my 2005. I learned in 1978 (from an "old timer") that the weep holes were causing the noise I was hearing. If one covers only the front weep hole completely and covers the rear weep hole with covers one can purchase from a dealer, there should be no problem with drainage. I keep my coaches over ten years each and drainage has never been a problem.

I had something almost like that on my old gas unit. What I found out, was were the dash topper is mounted to the fiber glass nose, the screws used at the factory was too short, and there were only 4 with a sealer holding the dash to the fiber glass. I removed all of those screws, cleaned the old sealer, opened the top from the fiber glass, put in new flex sealant, and almost twice the length screws. I put in about 12 screws and put sealant all around each screws. I then went to auto zone or any auto parts store, and bought about 6 cans of under coating (rubber type), and sprayed all around (under the dash topper), any cable or wire that ran through the fire wall area.

No more yelling while driving, and no more outside air coming in. AC works better in summer and the heat feels better went it's cold.

Good luck, hope this helps.
