This extended-length version of the Yukon is a twin of the Suburban.
Interior quality is good, and there is room for up to nine, but typical versions seat seven.
Unlike the Ford Expedition, the third-row seat sits too low and is uncomfortable.
The Yukon XL can tow a heavy trailer and swallow more cargo than most minivans.
The standard 5.3-liter V8 is just adequate and returned 14 mpg overall.
