If you get hit by a big truck, you're toast anyway, but in the average day to day collisions I believe one will fare well because of the mass of the truck and generally speaking, you're above the point of impact of most vehicles. That being said, on my own FG 140, I've installed a home built steel bumper of relatively substantial mass. Though I have no way of truly predicting how it will behave in a collision, I believe that it will spread much of the energy across the front of the lower part of the cab. There really is no "crumple zone" in a cabover is there? Maybe I'm a sick, addicted puppy/glutton for punishment...my first rig was a 1966 VW Bus.......first one at the scene of a crash, huh? :smiley_drive:
