We have a 2019 KZ and from what I have read on the internet it may have "dry fit" windows and the seals are leaking on a couple of them.
I ordered some butyl tape that is 1/8" thick. The TT has corrugated siding and the gap between the window frame and low part of the siding is just over 1/4". Do I need to triple layer the tape? Can I double layer the frame and add small sections in the low spots of the siding for the 3rd layer?
Yes that what I had to do for mine. Place the single layer all the way around onto the window frame itself and add appropriate sized small pieces to fill out the recessed areas on the trailer. When the butyl is warm, you can cut pieces lengthwise and roll them between your palms to make fat "worms" to fill in any gaps. Don't go gorilla tightening the screws, a little bit every day, some will ooze out you can slice off with a dull knife, gently. A good idea is to add a couple thin shims under the window frame from the inside opening to keep things square in the opening and it prevents the whole window from slowly sliding down.
