Utility Trailer Sides Flex

[Yard Elements]

I have an eagle ultra landscape trailer. Really nice trailer with plenty of room but I have the problem of the sides flexing when I use it to haul bark. The sides seem pretty durable but for some reason at points the sides flex out. how do I fix this? Thanks. Any one elese had this problem. This is a factory trailer and look very professional so i don't want to do any crazy jankey modes.

have you concidered a few ratchet straps across the bed when hauling your bark ?

guess I worded that wrong, they don't flex it's actually pretty heavy gauge steel, a few areas just pop out a little., and have to be hammered back in.

slide a couple sheets of plywood along the sides before you dump the bark in.

Oh so the pressure of the bark is popping the metal outwards?

I like the plywood idea. Why not try that out and let us know what you come up with.

pictures may help us understand a little better what is going on.
