Pick up bed dent a problem for a truck camper?

Truck campers do have pretty strong floor and mine is having 1 1/8" plywood that can be supported in just couple of points to hold whole weight.
So I would inspect camper floor to make sure it is solid and not worry abut bed dent.
I have Dodge bed on my F350 and the bed is costing me lot of troubles. Seem all the spot welds are cracking metal around and I had to straight it when I bought used bed.
Must be Dodge thing.
