Gear ratio is whole science.
I order my new F350 dually with lowest ratio the factory provides, yet hauling 18,000 lb total on California "killer grades" the engine is very happy at 1700 rpm and doesn't even think about downshifting.
I think I could use another overdrive even with cargo trailer.
I don't think anybody who can do simple math has illusion that diesel doesn't make sense on long run, but the $8000 up front cost when buying new truck will take long time to recoup for some.
Than when buying used truck, the price proportion is even bigger.
That all hinges on the cost per gallon of fuel and your average MPG.
