I'm kind of a scaredy cat. Since it's still a work truck I kinda like the idea of an all-steel bed,just in case the 'worst' happened.
The steel would wad up but it would absorb a lot of energy and would probably remain in one piece,containing the load.
A neighbor out here was rear-ended once,sending his work tools through the air.A few of them tried to go through him.
If I start from a Toyota bed,it will bolt right on,I'll have a tough floor,front bulkhead,integrated side posts,steel tailgate frame,and steel gate.
And if the new bed has no flexure,it will help protect the composite bedcover from deformation during chassis twist.
