    Road Test

    This big SUV, which is built on a full-sized pickup chassis, seems like a throwback in a world where nearly every other SUV is now based on a carlike unibody structure. It's a virtual twin of the Chevrolet Tahoe and essentially a shorter version of the GMC Yukon XL (and Chevy Suburban), with a 20-inch shorter length and about 24 cubic feet less cargo room.
