Given the workload and dynamic forces involved, I think the suspension is holding up pretty well.
Interesting observation
I would concur.
The dynamics at play here are considerable
The process of working out the moments around all the chassis and body structures while in motion would be considerable..
Considering the movement is three dimensional and also has obliques forces applied to the chassis and body, while vehicle is in motion.
Not to mention the free movement of unrestrained body component under acceleration and deceleration.
I will have to watch the clip again
