How to attach screen room to rv

[Jtrailer]

Have a travel trailer at campground permanently. How do I add/attach screen room to trailer? It will be mounted on deck but how to attach to trailer? Do I take off seeming and use the hardware attached to trailer to the screen room?? Patio mate type, aluminum frame , screens and a sliding door. Any help is appreciated

He’s good at sewing, with Velcro and tubing with channel, he put together a real nice little party deck
The atrium is a pop up kind and it sits on the deck, there are loops that are already on the atrium and honey add buttons for them to loop over.
It was not an easy project.
Had to add folding doors for privacy.
