All ties allow for some movement, but it is your truck bed bending.
I think you look in wrong direction.
And in this case, the truck bed is bending because it is the tie point. Just because the damages aren't at the connection doesn't mean that the forces don't originate there. The forces are distributed throughout the bed, and the weakest areas will show damage first. It'll just compound as time goes on. The bumper ties have nothing to do with it.
If you strengthen one area - in this example, by sandwiching the bulkhead between steel plates - the damage will just occur somewhere down the line.
