After watching the video, I'm wondering if you all took the weight of the panels into consideration. At the end it looks like you press buttons to make the wing close the rest of the way. Those panels are VERY heavy! I know, I've tried lifting mine! They might come crashing down on you, and pen you between the trailer and panels. Might want to do a test with panels tied on with ratchet straps. Just a thought! ☺
