I’m trying to assemble this trolly and the instructions are blatantly useless. Attempting to check it from the box picture, I was convinced that the washer goes on the nut side, but as I tried fitting one caster without even tightening it hard, I got a feeling that the railing got a bit crooked (it will be under load pressure) as the caster base isn’t wide enough and that if the washer goes to the inner side, it would provide more support to prevent the caster based wedge int the railing and bend it, but then the front and back heights won’t be the same, since the front side doesn’t have washers. I know we’re speaking about a few millimeters but still.
So which side do you think it should go?

It looks like the U-channel on that side came bent - If you compare it to the other side it seems to be bent quite a bit, judging from the pictures. This is why the caster plate isn't hitting the other side, and why you though to put the washers behind the plate. However, the washers are meant to go underneath the nut, not the plate. I would suggest trying to bend the channel back into shape - try using a hammer and a block of wood - place the block of wood on the side of the channel, and then whack the block of wood with the hammer. The block should help to minimize any distortion as you bend it back.
