Now, as an engineer let me explain something about GM accessories and in particular, the front brush guard.
You may not know, but there are two SIR front discriminating sensors in the front end of the vehicle. They are designed to signal the SDM (sensing and diagnostic module), the air bag controller, with information on the severity of a crash.
If the crash is extremely severe, you want the bag(s) to blow both stages to protect you. (The bags can deploy in one or two stages, stage one is not full force, stage two is maximum.)
If a front end piece is put on that is too stiff, it may not bend back correctly and not allow the sensors to react, thus not signaling the SDM.
GM's accessories have to pass a test that they will not interfere with any safety items.

Now, back to the salesman. As others have stated it sounds like BS. It is a brush guard it will push brush aside. If it was designed to push logs, boulders or cows, it would be called a log guard, boulder brush or cow scoop.
