Great Truck. Have had other Chevrolet Trucks and Ford and this far exceeds them all. Only one problem since new Speedometor went out. Wife caught that and got it fixed prior to me coming home. Tow 32ft. 5th wheel at 10,000# dry with no problem. Duramax/Allison combination good match. Sure would be nice if larger tires and sat higher but that is ones preferance can do later if want. Allison Trany shifting from stop slight roughness till warmed up just a few times but the sound is like a tank shifting into gear. Comfortable for long trips, good milage, good power and no problems really to worry about. Like to get a new one but this one has a long life in it.
Duramax, Allison, 6 cd, tow/haul mode, info center, good milage, OnStar, reliability, pulling power, foldown rear seat to put 42" new plasma TV in cab, storage behind rear seat and underneath, heated seats and outside mirrors, and rear window and much more.
Done in new models. Will get though this one will last a long, long time prior to that happening.
