Question: is a yukon a truck?
Answer: The GMC Yukon and Chevy Tahoe twins are well known. The Suburban and Yukon XL are those same trucks, stretched. That means you get the same truck-like, body-on-frame construction, burly V-8 powertrain and three rows of seats. The big difference is that the XL model has a lot of space behind that third row of seats.
