    I have the Express 1500, 5.3L 3.42 gear, AWD. I only have less than 100 miles so let me get some miles in and I will report back. Right now it is too early to tell.

    You can reset that onboard mpg any time you want if you want to see how you do on the highway or in city exclusively. I have been resetting it when I go on a long highway drive.
    I am getting 20+ mpg on the highway 65mph and a little over 15+ in mixed driving which is around town with city and highway.
    Overall I am getting over 15 which isn't too bad and that 20+ highway is nice. LOL HOPE the onboard is accurate!!!!
    I do drive slow and I am easy on the gas pedal and I like to coast a lot so maybe the way I drive is actually getting me those numbers #'s and the onboard pc is accurate. I will find out when I do my calculations.

    This is according to the onboard pc.
    I am going to start doing my own calculations as soon as I refill the tank with gas.


    Also how are you liking your Express AWD???? I had my Savana out in some deep snow up at Tahoe on an unplowed road (2+ feet deep with hacked up snow ruts) the other day. It chewed right through with the BFG's. Real nice.

    Update:
    After a couple of months MPG is between 11.5 and 13.5 depending on the right foot! Average is around 12.5. All driving is around town with some hwy and always with a full load of tools.
