I Did a few more test lifts with some dirt. made a few videos of how its working. I also got real lucky today that I didn't scratch it when I rolled it on its side. I was raising the box and manning the camera when it leaned to far and went over. Luckily the wheel top of stack, box side and mirror bracket took the hit. no paint damage! I will be adding more springs on the trailer and possible just put in a walking beam to help keep it more stable when raising the box. I noticed one of the arms is pushing harder than the other and think this is not helping the issue with leaning.
