These guards have been around a while for the H1. I think it's only keeping with tradition that some H3 owners would want to give their Hummer a goliath look like the some of the big daddy H1 owners have before them.
The functionality might be a pain, but I think Hummer enthusiasts (like the guys working in the service department) will understand.
Hinges in the front make me worried about hitting anything. Then again, H1's have winches on the front. So it's not a good idea to be bashing anything. Get a Ford pickup truck for that sort of thing.
The purpose of the guard is to protect a finish against brush and tree limbs when you're offroading (and to look badass when you're on the road!)
