A ranch I worked for had a bull bar... the bull won! Most are made too light to do much protection, sometimes cause more damage than without one... I had to pull that one away to be able to open the hood at all... but they do look pretty cool when not all bent to heck...
I was thinking of getting one but dont like the idea of removing the tow hooks since you never know if you need to use them. My luck if I remove thejm I will need them.
