How jacked up is this frame?

[PancakeMix]

I bought this frame for a '72 Chevy longbed. I can't tell if the frame is bent from moving it around the field for the past couple of decades, or if it's supposed to be that way.

Either way, it'll go to the frame shop to get checked and straightened out if it needs it.

The one that concerns me most is the area I circled in red. It looks too perfect to have been bent on accident that way, but it makes no sense to me why it would be bent that way. All the pictures I look at online don't appear to have it, but all I can find is 2WD truck frames.

Overall, the frame looks pretty straight to me. Kinda hard to see with the spare axle on top...

I need coffee.
