...the diesel Cruisers would be left alone sitting on US sales lots.
Speculation on both our parts. We'll never know and we have no sales figures to show one way or the other.
...you end up with a petrol that's trying to be as good as a diesel
That's really the nail for the hammer: gassers trying to be tow and off-hwy friendly where diesel fills the requirements.
It doesn't matter what you are doing, pulling, where the torque and/or HP curve is...the 5.7L blasts the crap out of the TD in every way except mileage.
Look at the curves, it doesn't have torque rise and the little it does is WAY high in revs. This is fine for the highway and ubiquitous desert rats where you and I both live. Shotts, I have to assume you've driven a proper diesel off-road?
