Too bad about the retention of the live rear axle. That should have been buried years ago. Pickups, yes, SUV's, no. It's like having rear drum brakes when the competition has four wheel discs . . . and then make excuses about tiny rolling resistance differences (which any driver could offset by smarter use).
But it'll have class-leading dashboard driver distractions
I'd say this about any brand, not just GM. Neither fish nor fowl.
The Halfback Van Conversion
looks better and better.
