I like the nerf bar idea too, but with my Body lift, the running boards are great for hiding the ugly frame underneath. I took the running boards off my Explorer when I lifted it, and from the side, the frame was all you noticed.
Ditto on the snow and mud getting all caught up in the wires. I have ice chunks hanging down to the ground from those wires for 4 months of the year. No matter how you tuck them up, they always seem to get pulled out by something lol.
But my vote would be for the nerf bars.
