I looked on Primitive's website, and although they didn't show one, I'm sure they make one that fits. The stouter of their designs mounts through the front bumper to the bumper beam mounting points.
It's not a push bar like cop cars have, but when I asked what they had, I told them I wanted to be able to annihilate a shopping cart (as a measurement, it works) and that's what they came up with...
Assuming a 3rd gen mounts the same, it would not affect approach angles and front clearance in any meaningful way, it's stout enough to stand on, and won't wobble when you drive on a rough surface with your lights on (that was what I really wanted.)
Negatives: They probably aren't cheap, and you will have to put holes in your front bumper to mount it. Not sure if they already make a 3rd gen (send them an e-mail.)
Positives: It's not built cheap. Sturdy as ****. They include a hole saw and tool to get the holes right in the bumper. (At least they did with mine.)
