Tried something new last trip.
I have a 2001 Ford Excursion V-10 with 4.30's. I tow with a small dual sport (230 cc) on the front of the truck. My TT is high profile and 33' in length.
I experimented with locking out OD, and setting the cruise at 58. WOW, what an easy tow. I was running just under 3,000 rpm and it pulled every interstate hill with no downshifting Gas mileage was around 7.8. It was getting around that before. Oil consumption was the same. A quart to Florida and a quart home. I'm guessing 2,900 rpm is a high torque area of the power curve.
If I don't use cruise my speed picks up so much it kills the mileage, although I'm sure it would do 65 with ease.
