The problem with "brush guards" is that while the protect the headlights/grill/rad from a frontal impact, they DON'T generally protect the bumper, particularly the lower/outer corners. I had a "small" accident with my 2011 1500 CC at 2-3 MPH and the stock "bright chrome" bumper folded like paper - instead of replacing it with a stock factory bumper and adding a 100# brush guard that wouldn't have saved my bumper in this particular collision anyway, I went with full replacement bumper by Tough Country. Not cheap ($1600 delivered with several custom options), but WAAAAAY more damage resistant.
Not my truck (as I just got the bumper installed 5 days ago, and where I live in Canada it's dark when I get up AND when I'm done work), but my bumper is identical to this, minus the fog lamp cutouts (my choice):
Bumper was a quick 90-minute install with no glitches and 2 friends - just unbolted the old-n-busted, my buddies lifted the new Tough Country Deluxe bumper into place while I pushed the bolts through and finger tightened them, then stood back and eyeballed the fit....took a second to break out a level, then tightened it all up. No reaming/drilling holes, no screwing around. Just easy-peasy.
