Something for you guys to think about....
hitting a deer with one of those is not much an issue, the truck will survive one of those run-ins easily.
here's the problem... when you hit a car, the impact energy has to go somewhere. If the bumper survives, the frame won't. Ther frame rails become "offset" or as i put it, "diamonded". A complete frame changeout will be required. Easiest way to tell is something like that has happened is to check the steering, it will be really off. This problem is very common with towtrucks due to the pushbumpers we like mounting on the fronts of our trucks.
