The appeal of three-row, full-size SUVs like the GMC Yukon is hard to deny. Even big families can ride in comfort and hitch a medium-size trailer for a cross-country trip. With the extended-length Yukon XL version, the SUV can accommodate a week's worth of luggage when all the seats are in use. Any of the Yukon's V8 and diesel engines could deliver satisfying performance, while available four-wheel drive can assist you through the snow or up a slippery boat ramp. Although the GMC Yukon and Chevrolet Tahoe are closely related, GMC buyers typically go for the higher-end amenities offered by the luxurious GMC Yukon Denali trim.
