    ok, so i went to the cape for the day, because my mom and brother are down there for the week, so i decided it was a good excuse to take the day off from work. it's roughly 3.5-4 hours each way, depending on how well i obey the speed limit. On the way down, i used cruise control the entire time(70 MPH) which kept me right up with the traffic, and i had the windows up and the A/C off. i only used about a 1/4 tank. I was freaking amazed when i filled up at the cape and calculated my average MPG, 19.94!!!!!!!!!!!!!!!!!:) :) :) :) :)

    i usually only get like 15 at the most, but that's around town driving. this was the first long trip i had made with this truck, and was pleasantly surprised. while at the cape, i used up about a 1/4 tank of fuel driving around, and driving in 4-hi, with deflated tires on the beach.(i aired them back up to 65 PSI when i was finished with the sand driving) on the way home however, i decided i was gonna enjoy the long drive a little more than on the way there. i had the windows down(rear slider open too) and didn't use cruise control, i used almost double the fuel that i had used going down. when it was all said and done, i put 658 miles on the truck in just over 15 hours, and averaged 16.2 MPG for the entire trip, which isn't bad, considering what i was doing.

    ***oh by the way, does anyone know of any good places to off road at the cape that don't require paying $50 for a permit?

    Are you running Load Range D or E tires? I am assuming you are talking about the GMC 1500 4x4. 65 psi is a lot for regular light truck tires, but I bet it would make for some stellar gas mileage.

    Would also ride like crap. I would rather be "not sweaty" than get 19.9 mpg vs. 17-18, which I got with my '03 5.3 Chevy.

    i had the windows down(rear slider open too) and didn't use cruise control, i used almost double the fuel that i had used going down.

    At highway speeds having the windows down uses approx. the same amount of fuel as having the AC on. :cry: So why not keep cool. :blob2:

    By the way what was the ocean temp at the cape?
