The Isuzu engine is the best part of this truck, along with the Allison tranny. The worst part has been all the GM stuff. Everything from numerous AC problems to leaks, memory features deleting themselves, multiple transfer case problems for auto 4WD, and leaking fuel injectors. If it were not for the dealership's attitude and incompetance i would buy again.
Nice for towing

This truck was bought for towing and does a great job pulling our fifth wheel camper.

Great engine and transmission combo. Duramax / Allison ran well for most of the 10 years I owned the truck. Was used as a work truck with a contractors body fitted. Weekends was used to haul a 3 horse trailer. It worked every day of it's life with me. Poor build quality was evident in the front hubs, bodywork (rusted cab corners and rocker panels, roof flexing with windows open) and cab interior (gauges gave up, blower motor repeatedly died, gauge cluster lights died one by one, headliner fell off). Diesels are expensive to maintain when things go wrong, in my neighborhood it is hard to find a reputable diesel mechanic. Normal maintenance (oil change etc.) is probably more expensive but less frequent. All in all a very reliable truck that felt more like a car to drive.

I have owned my gmc for a short while and am very pleased with the Duramax/Allison combination,I have owned powerstrokes in the past,the difference is amazing, the Duramax power range extends for a much longer time, torque is great.Allison transmission holds gear going down steep grades and the mileage for a full size pickup is awesome (average is 18 mpg, I have gotten as high as 21 mpg)

Bought this last May, love the Duramax/Allison Combo - pulls my 10000 pound 5th wheel like it wasn't there. 12 MPG @ 65 MPH - nooo problem. Very stable on the road.
