Well, I'm a little confused, so help me out, and maybe others. You have a Hybrid camper. It may help to know make and model. You have a "floating deck", assume that is free standing? In other words, not attached to the camper? You have a "screen room". Is the screen canvas or fold able screen material? Does it attach to the awning? Does the deck have a roof?
Sorry, there are many combinations, and a lot of stuff out there. A few more details, and maybe even a pic or two, will get you some more help, I'm sure. Hope you enjoy, and Happy New Year.
