In either version, the third-row seat doesn't actually fold into the floor when not in use; it needs to be lifted out of the vehicle, which is really a job for two people. With the third row removed and the second row folded, the Yukon XL has a huge 137.2 cubic feet of cargo space, and there's still respectable room for cargo with people in all three rows. Keep in mind that in the standard-length version, there's very little space behind the last row; it has 108.9 cubic feet with the second and third rows down, but just 16.9 cubic feet with the third-row seat raised.
Another problem with the Yukon XL's length is that many city dwellers or even those who frequent shopping malls might find it simply too large to fit easily into conventional parking spaces—or maneuver through tight city streets.
Ride quality in the Yukon is quite good throughout the model line, with most trims having a nicely damped, almost carlike ride—only cornering on choppy surfaces, or railroad crossings, will remind you that it's actually a body-on-frame truck. Fit and finish inside is generally top-notch, the interior is pleasantly free of wind and road noise.
