If not i just cut the verticle supports another inch shorter so it overlapps 2 inches. A 1inch gap is a bit big for weatherstripping but your right-shims will squeak. I think i will have to do some experimenting, so thanks for the ideas. I will try a few different things to see what works best probably after i finish this tongue box and doors. The foam would probably squeak too, hmm...
Okay, the 1" overlap may be good for keeping water out but cold air coming through the 1" gap could make it pretty drafty. But, that 1x1" overlap x gap may be to your advantage! This is because you can get 1/2" thick and wide foam weatherstripping. So, if you put a strip of that at the very top of the outside side of the stationary "box" and a strip at the very bottom of the inside side of the lifting "box" so that they meet like two fists knocking on each other or maybe touching but not scraping each other, it might work. Here's one that you could tack or glue on; but, you'd have to use a couple pieces to make your length:

There are other types of foam weather stripping that don't scrape or make noise. The problem is that the sellers don't usually give all the measurements or they give them but don't say which is width and which is thickness. Your best bet may be to go to the hardware store and look. Your good fortune is that hardware stores usually restock this stuff in the fall; so, you should have a good selection of products to look at. Foam weatherstripping doesn't make much noise, if any, when it rubs. It isn't like Styrofoam.
It could be pretty drafty on a windy day i suppose, i had imagined it wouldnt be any worse than a tent but maybe it will. I had planned to bring enough long towels or something we could roll up along one side on a windy day, but firther planning for that may be nessacary. Will have to test first.
I know weatherstripping wont squeak but you had mentioned styrofoam at one point, thats what i was referring to.
The weatherstripping on each side may not work because of how we are doing the screen unless i lower it an inch or so, when the sceen is on we will have to set it up on a windier day and see what it takes to stop the rocking.
Hardware stores are packing themselves full of it already
been looking at different options for sealing my doors. This is my tongue box when sealing it yesterday.

You “Can” , but doesn’t mean it’s going to work all the time … Most primers we’ve used are shellac( alcohol) based or water based primers … Both of which will accept latex paint on top … When we painted Latex over
