I was going to say the exact same thing.

Block of wood between the cab and door, and start shutting the door.

Obviously, be gentle on the cab.

I just did this a few weeks ago.

I hope this is what you're asking.

If it's bent out instead of in, I would imagine you could do the opposite. Get it off the truck and on the ground. I'd probably put something soft under the main body of the door, then a block of wood under the outer most bent corner of the window frame, and start putting my body weight on the area where the window frame and main part of the door meet.

Go slow...be patient.
