I have to say my experience with my GMC has been awesome. I have travelled over 17,000 miles since I first got it. It hauls my 42' 5th wheel with no difficulty and my daughter enjoys the DVD system w/the wireless headphones only a little more than I do. Great sound system and entertainment system. Shocks are a little stiff but only when I'm not hauling. I did a lot of comparision shopping and my GMC had the most options for the best price.

2007 GMC 3500 carbon monoxide in cab.

Having driven this truck only a short distance, 2400 miles, problems are already evident. The worst being a diagnosis, from a blood sample test, of carbon monoxide poisoning due to cab infilteration. This is caused by the missfiring of the injection electronics package and the poor cab fit and finish allowing the engine exhaust to get into the cab unless the recirculate mode is used on the heating system. Recirculate is defeated by the controller which will not allow the recirculate mode to be engaged except on max ac. The engine has very poor throttle response and smokes excessively under heavy acceleration. The engine has a propensity to consume oil.

Only problem has been the left door speaker went bad. Only thing I don't like about it is that the rear springs clunk with just the camper on some bumps at lower speeds
