Just found this site through a link off another. My wife and I have an 04 Denali. So far it has been excellent short of a random and weird Nav disc error deal. It is my wife's business car. My daughters love it. I like the power and it's road manners. I have not towed our boat with it yet as we typically use my 01 K3500 CC LB Dually. It is the Duramax Diesel/Allison Trans option and tows the boat like it is not even behind the truck. Plus the truck gets 16mpg towing. I have heard that the Denali gets less than 10mpg towing. I know so far it averages 13-14 daily driving.
