I honestly wanted one for a long time but then learned that I'd be better off simply replacing the bumper and grill with something that doesn't need guarding. I can see it protecting the headlights from small branches and such, but a big hit is just going to shove that steel into the plastic behind it anyway. Now you have a damaged body and a bent brush guard. They're also not kind to the approach angle, and with my truck I have to be extra careful about the angles.
But it's your truck. I'm sure some of the stuff I'm doing to mine raises eyebrows. Besides, as a frequent Reddit user, I can confidently say that there's never a shortage of confident opinions.
