Recently bought a tundra and I'm debating a grille guard - living in WY, chances are one of these days I'll hit a critter. Do they protect your truck/are they worth it? What are the best brands to consider? Does a well made/heavy duty one make 1/2 ton truck ride lower on the front end? I actually prefer how the truck looks w/o the guard - so this is basically a protection decision for me. Thanks for your opinions.
