The biggest disadvantage to the Yukon's third-row seating is the amount of cargo space that gets eaten up in the standard-length models, though a high liftover height is also problematic when loading heavy items. With the third-row in use, very little cargo space is available between the seatback and the tailgate. Tumble the third-row seats forward or remove them completely and a substantial amount of additional space is at your disposal. Note that removing the two rearmost seats is awkward and requires some light lifting, and that GMC doesn't offer power third-row folding seats. By contrast, top trims of the Ford Expedition and all Lincoln Navigators have third-row seats that fold into the floor in addition to power third-row folding. On the GMC's positive side, the power tailgate takes the stretch and strain out of raising and lowering the tailgate, and in its raised position is out of the way even for taller people.
