I don't know. My wife would like a Trailblazer sized vehicle with a turbo diesel. However, Chevy is offereing a 7 pax 4WD trailblazer with the 5.3 engine. That is an awesome gas engine. I'm thinking of a 3.73 rear end and the 5.3 for her. the think would fly, and most likely--based on the results I got with my '01 ext cab Z-71 with the same motor--get 14-15 mpg in town and 21-22 on the freeway. Of course, I'd rather have that same vehicle with a 5.0 liter V-6 Dmax tubro diesel...............
