0-60 doesn't mean a whole lot to me. My 03 Duramax is tuned and does 0-60 in 7 seconds. It is not even in the same league as the new trucks as far as towing goes. Racing flat out up an eight mile long hill is a little better measure of a trucks towing ability but just because truck A is faster up one hill than truck b it doesn't mean it will be faster up the next hill. As well if my Ford goes up a hill at 55 mph and 2200 rpm and a GMC will go up the same hill in 3rd gear at 57 mph and 2950 rpm I might very well enjoy my towing experience more in the slower Ford.
