2007 4dr SUV 285-hp 4.2L I6 4-sp automatic 4WD w/low range Avg. 15.5 in mostly in town driving. 21.0 best on long trip with light load.
2004 4dr SUV, ext. 300-hp 5.3L V8 4-sp automatic 4WD w/low range 16 mpg nothing to write home about, but acceptable for a vehicle of this size, weight and capability.
2002 4dr SUV 285-hp 4.2L I6 4-sp automatic 4WD w/low range I recently purchased slightly larger tires and my fuel economy is suffering by 10% compared to stock tires, but I was anticipating this anyway.
