I figured out some of the dynamics of the crash by taking the trailer apart, piece by piece.
I couldn't figure out how the ramps got so badly bent. If you look to the upper left ramp you'll see the pulley that the garage door springs attach to. There's a perfect imprint of that pully in the white panel next to it.
What I can discern is that the Porsche stayed put until I hit the concrete median. It slid sideways with that impact, but didn't hit the wall. When I hit the guard rail the impact was much greater and the restraints tore loose allowing the passenger side of the Porsche to impact the inside of the trailer wall. That impact pulled the trailer top over so far that the opposite wall pushed the ramps out of whack. It also left the rear opening 3/8" out of square.
I used the same method I used to straighten the ramps to straighten the body. I made a "hand" that would grasp the top of the trailer and pull it up straight. I fitted a piece of wood to a piece of Unistrut. The "hand" would distribute its pull over a 24" area but I didn't want to scuff or dent the polished metal so I covered it in polishing cloths.
I installed it in the appropriated location and drilled another hole in the side wall to set an anchor to attach the come-along.
I had to pull the body back 3" in order to restore the 3/8" gap. The structure is so strong I could hardly get it to budge. After several attempts it sprung back into the proper configuration. All that to move the trailer 3/8".
I removed the damaged lower trim piece from the drivers side and hammered it out smooth and sanded it out in preparation for polish.
