Re:Concession windows in trailer
There are several DIY build threads going on here with lots of pictures. Look through the last few pages of this forum, you will find them.

Go to google, enter road food and your search word, seems to pull some stuff.
There is challenger windows in Indiana for your concession window, do a search for them too.
