I replaced one of mine. Here is the link.
Just replaced front bunk door on 2010 Roo 17
It wasn't as difficult as I was afraid of. Just take pics as you remove the old one to reference. It is so much better now. I believe the tape went between the camper and the long hinge.
It's like new now. Good luck!
