I wouldn't call it a technicality. It's written right there on the GMC site -

CHASSIS PACKAGE Suspension Package, , Off-Road (Z71)

and there is no charge for the skid plate package -

SKID PLATE, OFF-ROAD Skid Plate Package, includes aluminum front underbody shield starting behind front bumper and running to first cross-member, protecting front underbody, oil pan, differential case and transfer case, frame-mounted shields (NZZ) $0.00

And it is exactly the package I originally asked about because I wasn't aware there was a difference between GMC and Chevy. And besides, who the heck wants fender flares! Especailly on a Denali.

Sorry my man. I think you were wrong on this one.
