You are damn lucky your mill got home OK. Two of your 3 tie-downs

I neglected to mention, the knee was locked. And only 1 of the 3 depended
on it. But you raise a valid point.

Next time you move a knee mill, place a block of wood on the base under the
knee. Then run the knee down onto the block, then lock the knee. Noticed the
boards on the trailer distorting under loading from binders. A couple 4x4s
lagged or thru-bolted to the base spreads the load out nicely, and enhances
stability.
