The first version of the trailer with hinges. It was too floppy.
| 
A little bit thicker bars. Still too floppy.
| 
| 
I tested with some technic lift arms. No good.
| 
| 
With normal plates. A little better.
The final version (on the top of this page) has 2 wide bars.
| 
| 
| 
The first version of the arm hinge.
| 
| 
| 
| 
| 
The final version where the hinge is 2 stud further from the center.
