Can any help? Trailer issues

On the second picture I see deformity inside the side panel that is generating a sort of damage as if it is swelling up.

 

The box mounts look to be factory. My 2cents is on the tire size has been changed from the original.

 

So here's what I'm seeing outta this post above...

Take all 8 decent tires off, spend 2 to 3 grand a on a WHOLE set of tires so you can get a couple of old tool boxes to clear the tires, Instead of swingin past a shop, pay an hour labor and have them remove them, put up on the deck until you get home to throw them outside or in your barn or sell them.

Low pro tires on a flatbed? Why....

 

The box. The metal on the end plate show a deformity.

 

Why? Just move the boxes.... It would be so much simpler and cheaper.......

 

I thought that too, at first. But looking at it on my PC screen, rather than on the tablet, I think what we're seeing, is shadow.
