Wiley Window storage question

I have my Wiley windows in and functioning, but, I need to get some ideas of how to "lock" them in place when trailering and camping. I'm currently using a couple clamps to keep the wedges in place while trailering. I'd like to come up with an easy to lock technique to hold the wedges so they don't fall out. Here's a couple photos to give you some ideas of what I'm looking at...
Closed in stored position

Open in use

And here's the clamps in the open position, however, I can't close the door while clamped. Any ideas would be great!
