I've never understood the use of grill guards except as a way to mount lights. The only thing they can protect the grill from is a small deer. If headed for Alaska you're going to have Elk, Caribou, Moose, Bison, Grizzlies, and large Black Bears. The grill guard isn't going to protect the truck from any of them. If you hit one, you'll just have a ruined grill guard plus the front end of the truck.
They do look nice though.
