Builder said:I would suggest that, too. Look for a 1-2 yr old diesel. That way you get the allison, and it will have a ton of warranty left on it.
Either that, or wait a little longer. GM will probably be installing the 6.2L V-8 with over 400HP for the '09 model year. It's already in the Tahoe.
You can check here to see some of the changes for '09: http://www.gmfleet.com/pdf/2009_car_and_truck_guide.pdf
