well, u could go with roadarmour but they are about 2 grand per bumper, but it has a cage that wraps over the hood.
if you arne't interested in that, your best bet would just be a mopar brush gaurd like i have or somethin of the like.
i dont know if any of you guys remember or not, but there was a picture of a durango t-boning a armored bank truck. it flipped the truck and did some damage to the durango, but mostly to the brush gaurd, all the body panels were good except for the drivers fender and windshield. that's pretty good crash protection IMO and in comparison a deer shouldn't be much of a problem.
