Re:steel supports
The bed is lowered by "jacks", one one drivers side and one on passenger side; as these jacks extend and lower the bed, the bed unfolds -
As it unfolds, the passenger side of the bed appears to hang lower while descending tilting the drivers side over too far causing the damage.
I am unsure how these supports affixed to the bed frames edges/sides prevents the misalignment...
