Trailer awning cold frame?

It's an unfortunate sign of times but in our area we have many camp trailers that have been abandoned in the woods here. The Forest Service has them hauled off by local tow companies and scrappers. I got a nice awning for my skoolie project for nothing and a set of the hardware without the awning. I wonder if I used greenhouse plastic in place of the awning fabric then mounted it low on the side of the shop how it would work as a seasonal cold frame.

It would probably be pretty good :)

I'm not sure the angle of the awning sides, but a really cool idea (stolen from Swedish Family Homestead a long time ago) is to make the sides solid, and then attach a decently heavy board to the top and bottom of the plastic. The top attaches to the frame or house, and the board on the bottom hangs off the edge. If you get the right weight board and right height, the weight of the board holds the plastic in place, but still makes it really easy to move to get into the cold frame.

**Edit Here is a link to a video where you can see it. I forgot he also added some supports in the middle for weight and structure. I just like that you can roll it up and not have to worry about hinges or doors or whatever.

The geometry of the awning angle would depend on bed width. Lower legs could be cut to that dimension. The hardware was free, so I'll fiddle with it.
