I hit deer at 60 mph with 1999 F450. Small Montana highway at 10 PM.
The truck had very strong factory bumper, what sacrifice itself to protect the row of radiators behind.
It was not a pleasant experience.
I was researching front guard mainly for front hitch on my new truck and there is lot of stuff that "hangs on front grille".
Good stuff like ranchhand.com/ford.html, hammerheadarmor.com not only adds 100's of lb to the truck, but cost hefty money.
With my camper setup - I carry Honda 3000 on front hitch.
How much that would protect the radiator in collision with deer at 60 mph?
Hope to never find out.
