This has been almost trouble free. The one area of trouble was taken care of by GM with an extended warrenty of 200,000 miles on the injectors. Getting an overall mileage of 17.5mpg, with some tanks going into the 20 + when driving all e-way, even at a steady 75+ MPH. The diesel pulling power is great. I towed 18,000 lbs from Sarasota Fl. to Phila. Pa. and averaged 12.2 mpg.
Truck tracks very good on the road. Tire wear is minimal, as it holds alignment well. Seats are great for long trips.
The turning radius is terrible. I sometimes need to back up 2-3 times to park in tigkt spots. Places where my Yukon XL goes in in one pass. Whindshield wipers need more glass pressure. Fuel filter changes are a pain, and could be solved with a larger capacity.
