I did a similar move but with my 5th wheel and it's by far easiest to just get a new one. When I compressed the top, the black piece with the handle, key and camera got forced out 1/4" or so. I opened it up and there are some really beefy ridged stiffener pieces to keep the top of the gate strong. Basically, there is no way to bend them back. Maybe some Bondo but that's probably more trouble and kind of a crappy repair. My auto body buddy said the raw gate (without camera, etc.) is around 800-1000 but pretty difficult to find. Painting would be another 400-500 he thought. I'm not sure if he was giving me a deal or if that is full retail. When I realized it was more than 1000 I tuned out and decided to just live with it. Mine is much less noticeable than yours as the damage was under the plastic strip (which I replaced - got it at the dealer for around $75). My biggest issue is the handle piece being pushed out and the lock not working. Camera is fine... thankfully.
