the mud guards are very heavy and are attached to the mesh of the bottom tier.i think over the years it probably has been banged a few times and pushed the mesh in.it has also had a few quick patch up jobs done to it along the way by the look of it,i believe that the mudguards and the mesh on the bottom tier should be stripped out and replaced on both sides,if you are able to weld i dont think it would be a hard job to do except for the cost of mesh and metal for mudguards.i will take some new photos tommorow,some further close ups of damage and with the sides down also.the trailer has only been in my possession for about 6 months,i have,nt used it myself,but i did pull it from the old owners to my house and i couldnt relly feel it on the back end of my car.it was empty i dont know what it would be like full.
