In the TFL towing tests, the 7.3 got 2.2mpg going up the Ike. The diesels didn't do much better (all were towing 16K lbs). But they used the computer calculated mileage so take those numbers with a grain of salt. The big advantage to the diesels was in the downhill run. Far less touches of the brakes in the diesel trucks.
Interesting. Diesel are not know for good engine braking !
Did I read this wrong, "Diesel are not know for good engine braking!" We had a 6.8L gas and it was not good for mountain driving. A "seat of your pants" type of thing. Fast forward to our current TV - a delight up and down steep mountains - in Tow Haul mode, a touch of the brakes, slows it down, another touch of the brakes, and slows it down even more.
