I may be in the minority here, but I have a large GM SUV and now a Titan. My SUV has the 6L motor in it with 3.73 gears. The 6L motor makes more HP and similar tq to the 5.6L in the Titan, but because of the weight differences, the Titan would be the winner if they lined up for a drag race.
I do agree that the 5.3L motor in the 1500 pickups is weak compared to the Titan. I'd rather hook a trailer behind my Titan than a 1500 GM 5.3L pickup
And to keep up with the GM bashing, I think I read somewhere that the Titan accelerates within a .10 in the 1/4 to Silverado SS, which has fulltime AWD and the 345hp version of GMs 6L V8.
