Kestrel Take
Maximum space and towing in a plush package — the extended Yukon XL swallows people, cargo, and trailers, with the 5.3L (or 6.2L) V8 on the proven GM truck platform. Same 5.3L AFM lifter watch-item as the Tahoe, plus the extra cost of feeding and shoeing something this big. A superb long-haul family/tow rig if the V8 and electronics check out.
