Right you are. Didn't spot that - too much Christmas cheer, I guess.
But if the front shell didn't hit it on the way down, and nothing else is in range to touch it, then I am like you - I got nuthin'. And I'm not sure how a lift arm mis-adjustment could be related. The edges of the crease look dead straight, so I'm not sure how a misplaced torque could have caused it. I can't even think of a way that a skewed bed slide could have done that.
I guess my money is on some external source of pressure from some square-edged object or device. A car door? Something in the garage as the TM was backed in and turned a bit?
