Just wanted to share my experience with replacing my bunk end tents on my Roo 23ss.
My current tents unfortunately were damaged by mice and needed replacing. I decided to add vinyl windows to all three bunk end windows.
I used Idaho Canvas Replacements to do the work.
Clamp the top edge to the rain gutter, leave slack for installing the rubber bead.
Apply bead of silicone between metal grove and black rubber seal.
Use push stick to incert rubber edge bead into metal track.
Apply bead of silicone and smooth out after tent edge is secure
Repeat same steps for side tent bead edges
Reattach screw at bottom of inside tent track.
Finish bunk end fro inside
