Pictures please! I'm going to guess you hit the Tahoe with the headlight protection part of the bumper. (Let me know if I'm wrong) If you hit the tahoe with the actual Bumper part of the shrock I'd have a hard time believing that it cause that much damage. A regular brush guard will fold into your hood and damage the truck regaurdless of where the contact is made. I'm sorry to hear that you crashed your truck though thats never funny. In the fire academy we were taught that the airbags won't deploy unless your driving atleast 30MPH..
