Tomorrow (friday),I will make a small trip until sunday.
After, I will take a couple of pics and I'll show you the way we made (my wife accept my help ...)this screen door. I promise you !
With my Casita's square RV door (instead of the nice, curved ones on some of the models) a door like yours would be a nice upgrade, if I ever need to replace the screen door I've got!
Thanks for posting. Can hardly wait to hear more of the details!
