What was interesting is that I was stuck for 10 miles on a construction project road and had to do 50 mph. I averaged 28 mpg during that stretch.

But there is no way I was going to do 50 mph for 1600 miles. LOL

Curious...... can you describe your truck: is it a 4x4 and what's the axle ratio, and do you have a 4 or a 6 speed transmision?

My truck is a 4 x 2 with a 3.15 axle ratio. 6 speed transmission I believe.

Sludgy, your truck a Supercab 4x4 with 3.73 Gears correct?

Extended cab, not supercab. 3.73 axles.

BTW, Ford doesn't offer limited a slip diff in the rear with the 3.7 L. But I insisted and the dealer, Quirk Ford, installed a factory unit before I took delivery.

The 3.7 liter V6 is alloy, very light compared to a typical truck engine. So, with better weight distribution at the motor, more mass over the rear wheels from the extended cab, and the limited slip, the traction in 2wd has been outstanding. It has Michelin on-off road tires.

I recently drove off road in Maine, not even shifting into 4wd except in some really rough spots. At one particularly difficult hill, I forgot to shift into 4wd, and it climbed up as though it was in 4wd. I'm happy with this truck so far.
