Air bags not going off doesn't really tell that much. I've seen some very hard hits that the bags don't go off, and light hits where they do.
Just looking at it from the pics and making a quick judgment call I will say it's got frame damage. Probably quite a bit of diamond and the frame is in tension of some sort now. Notice how in the last pic the rear wheel is close to the front of the wheel well and the ass end is kicked up? Notice too in the front how the damage on the fender starts low and the compression goes more up than back? I would bet it it hit something like going off road and hitting a berm and stopping. Whole truck is in a twist of sorts. Ford uses a lot of HSLA in the frame so that means you can't really pull them. There is also a significant mix of different steels on the frame so some of it may be repairable and some may not. Barring having the ford supplied repair manuals you are just guessing. Prime indication though of HSLA is when trying to pull it on the frame machine and it won't move at the damaged area. Once they move due to crash damage, HSLA frames work harden and take a set. You may get some of it out but usually you can't get all of it out. I suspect that truck has significant frame damage. If you use heat to help move it you weaken it.
And same things said above apply to the front inner structure behind that fender. I can guarantee it's more than just the fender.Only way to tell is to thoroughly inspect it. Any frame damage on an HSLA frame would make it a no go IMO.
