Thanks. I'm not exactly sure what you are asking so I will show the drawing that I made of it. If this doesn't answer your question, please ask again.
Now, if I were to do it again, I would change a couple of things that I did and I probably still will when I put the motor on it. I have 1 piece of #8 all thread in the middle that screws it in and out. When I go in and out it cocks a little. Not enough to hurt anything but I notice it. I would go with one piece of acme all thread on each side so it will slide out and in perfectly straight. It would be easy enough to make the go in and out together using a chain and sprockets. I will more than likely do this to mine when I get everything else done.
The second thing I would do is definitely get the slide out seal first before you frame out. I had one I started with and have since scrapped it for something completely different. Needless to say we didn't get everything done this weekend I wanted to because I spent so much time with trial and error on seals.
Now to what we did get done. First thing we boxed in the slideout with luan so we could cover it in the aluminum.
I then covered the bottom first. We used contact cement to hold it onalong with a few staples in places that should never see weather. Notice the carpet squares that the plywood on the bottom slide on across the vinyl floor in the camper.
I then covered the side walls and made a bend on the bottom to overlap the bottom piece and sealed it up before I stapled it.
Here's a better picture of the other side wall. You can also see the bend on the outside that will be used to hold the trim and to help seal it off later. You can also see my mockup of the outside trim piece. The way it is bent, there really should be no way for it to leak.
This is what I am talking about, the way the walls are bent out and the trim is bent in, it shouldn't leak without sealer but we are using it anyway.
This is the seal I started with. That has since been scrapped. I found that a bottom garage door seal should work pretty good. I didn't get a pic of that but I only did one side with it so when I do the others I will get it.
Here the sides were done and we slide the box back into place. We did the top like the side, by bending them over and sealing them. I also have the top slanted towards the outside to deflect any rain. I am also going to put a gutter (deflector?) above it so that should do it. Hopefully anyway.
Here the siding is made and installed. All wood has now been covered and sealed on the slideout.
I didn't take any pics of the roof install, it was basically insulating it, cover it with luan and then gluing the rubber roof. Nothing special there. I actually had some help today beside the little woman so I took advantage of it. I still need to trim the roof material and finish stapling it all around and get the trim up but this old man is tired today so I quit. Will do it later this week.
Here's the other side with the window and the trim on the sides of the slide out. I wanted to have all of this as well as the roof and trim done this weekend but I spent so much time trying to figure out seals, we just ran out of time.
