Kirk W Thank you so much for the info. I do not believe I will be using the roof tape method. Also I have not used butyl tape before now. Is doubling up on the butyl tape overkill or not worth it? I am one of those people that over do something to prevent further problems. Or as I have had ingrained in my brain, "do it right the first time"

I have recently purchased a 99 Shasta E450 30.1. it has some rot issues I am rebuilding around the cabover bunk. This is my first RV I have rebuilt a pop up and other travel trailers in the past. Doing the work does not scare me, I just haven't worked on one of these. My question is, the exterior side wall and the under side panel above the cab and where the front wraps under by the cab. When taking the metal strips off and using butyl tape to replace, why can't you use the "roof tape to seal the seams as well before screwing the strip back on? Wouldn't that be an extra protection from leaks? I have also heard that the cabover window is most likely the culprit for the leaks. After I do all this work is there a way to fix that? the window has a crack in it anyway. Is it easier to replace and where do I get it or take the window out completely and fill in with something? Im sure I will have more questions as I am new to this vehicle. Any assistance (pictures, information, videos, etc.) will be greatly appreciated. Thanks in advance
