A small point that has nothing to do with the main argument:Ford also has a high idle option so that if you need a lot of power you can be running the engine at a ramped up idle as required for the current draw.
I don't know enough about big Ford trucks to know if my experience is relevant, but for what it's worth . . . I paid considerable extra money to add high idle programming to my Sprinter camper so I could recharge the house battery bank off the alternator. But after a couple of experiments, I never used it because the noise of running my engine at 2K rpms with no load for many minutes was so annoying when camping. I ended up just carrying a small Honda generator and found that much less intrusive.
