The concern, if I recall correctly, is that anything in the hitch that gets hit will transfer all of the energy of the accident directly to the frame of the vehicle making it much worse than a normal rear end collision. With nothing in the hitch, the truck and bumper compress as intended by the manufacturer to help prevent injury to the passengers, not the vehicle.

The gorino sounds like it does great for protecting your vehicle, but I would imagine a hard rear end collision would transfer much more energy to the passengers than without.

Perhaps the superbumper guy can modify his design a bit to match what others like.

I like the look of my sparebumper, but I know some might not. I think it looks like "Thor's Hammer". Adds to the look of my truck.
