I owned an early 2001 HD 2500 with an 8.1/Allison. While solid, fuel consumption, oil use, and piston slap made ownership less than desirable. After several years of Toyota and Nissan ownership, I ordered a 2011 GMC Duramax SLT Crew. The 2001 and 2011 are similar in ride and appearance, but power from the 2011 is considerably greater. The Duramax is quiet and interior noise is low. It has impressive electronics, and fit and finish appear excellent. Interior is nice but lacks appointments. Other than the large center console, there is limited storage for small items such as sunglasses. The exterior lacks tie downs and storage. This is my sixth GMC and first one in ten years. I'm back!
Power, gas mileage, On-star, satellite phone, Bluetooth, heated seats, back-up camera, quiet interior, rear seat legroom, fit and finish,
Needs overhead console for storage. The 2.5" receiver seems impressive but hole for the hitch is too far forward to allow a hitch cover to be installed. Needs more tie downs in the bed. Needs under seat storage for tow ropes and other items. Would like bed rail caps to protect the finish.
