This extended-length version of the Yukon is a sibling of the Chevrolet Suburban.
It can tow a heavy trailer and swallow more cargo than most minivans, with room for up to nine occupants.
The cabin is quiet, but the low third-row seat is uncomfortable.
Handling is cumbersome, and the steering is vague.
The 5.3-liter V8 is adequate and returned 14 mpg overall.
