I moved an '07 G7 a couple of winters ago with my ARB with minor body damage and a replaced bumper on mine, back end rebuild on his. The trees have barely made a scratch in the powdercoat when I've slid down trails etc. Oh, and the new one has reinforcing that may have reduced or eliminated the body damage I did receive.
There are some other pretty cool bumpers out there for what you'd pay for an ARB tho.
