All I can say is.....Sweeeeeet! .... 16 MPG, and 23+ when she breaks in. 500 HP and 450lbs of torque with a chip. Unbelievable off the line speed and power. Now I gotsta add a Greasel kit and run this puppy for free too!
So, what do you tow your Mac with out there?
I slightly regret to report: "2003 Sierra 1500 X-cab, 5.3L gas, 3.73 gears"
This truck is a dream to drive, ample for towing the Mac and the Quadrasteer provides incredible handling in tight quarters. Unfortunately, it "self-steers" into every fuel station it "sees!" I get 12 mpg average, towing or not. With nothing in tow it gets up to 15 mpg at 70, possibly 18 mpg if I hold speed <60.
My dilemma was choosing between the Duramax and Quadrasteer, mutually exclusive options. Pricing was about $45k (invoice +500 +tax for the Governator, net of rebate, fancy wheels & extended wty). I have an acquaintance with a 2004 Duramax CrewCab who reports 14 mpg, another w/ Sierra 1500 5.3L (StdCab, short bed & 3.42) who reports 18+ mpg.
I wouldn't want to give-up the Q-Steer, but sure wish the D-Max came with it! However, I'm almost certain that the Q-Steer can't handle the torque. What's a widget-weenie to do??
