Thought it might be a good idea to hit you guys up with what I am thinking and get your thoughts, insights before I begin production.
The room needs to attach to the camper, and needs to be cat-proof (meaning my cat can't get out). This will be a safety net to catch him if he bolts when I go in and out the camper as well as an outdoor space for him to hang out (and to keep the litter box). FYI, I'm considering using the curb-side storage hatch as a "cat door," access for Spencer to go in and out through the kitchen cabinet.
Here is what I'm thinking:
Using a 10x10 EZ up screen room panel (it's a 40' continuous run screen with 6" of Nylon fabric on top and bottom edges), I think I'll sew a tarp to the bottom as a floor. Or else just extend the length of the fabric on the bottom of the screen so I can tuck it under a patio rug to keep Spencer from being able to escape under the screen walls.
I will use the camper awning as the roof. To keep the screen attached to the sides of the camper I will sew pockets along the vertical edges of the screen and run a bungee cord that I will hook into holes that are already in the awning container and to the underside of the camper somewhere.
I am undecided about how to hook the top of the screen to the awning sides. I thought about alligator clips or similar, but wonder if they will pull off in a strong wind. Running a bungee from the camper to the awning legs does not sound good to me, because of the tension the bungees will put on the legs/awning pulling it back toward the camper. Maybe that's not an issue if the rafters are locked?
I don't know what I will do to attach the screen to the front, since the groove in the awning tube seems uncooperative. Maybe a bungee along the tube.
Regarding the underside of the camper, I have some strong magnets with hooks on them that feel like a strong bond on the steel chassis of the camper. I will extend the tarp floor under the camper (with a slit to get around the wheel) and scoop it up and attach to the chassis. I will also have to do some creative cutting/sewing of the screen to extend the side walls under the camper as well.
I know you guys will see faults in my idea and possible improvements based on your experiences. Please let me know what you think!
