Assembling bit tricky

Have the assembly instructions from one of the other reviews used. So it was pretty easy. Was not quite fit in the end, we did hammer out anyway. Meanwhile, I have the trailer improved by a wooden panel in the back and had already replace the tires, because I already had a flat tire. Now use solid rubber wheels. Moreover, the sapwood, which certainly solved the bolt on the tow bar and thus I've lost the trailer. I have now secured by a wire.
Overall, the trailer is ok, at least for the price.
