Even the tiny base V6's are making 150Hp by 2500rpm. That is sufficient to tow most 1/2 ton towable trailers. Is it really a big deal to run at 2500 rpm vs 1900? Really? And the diesel is at "full throttle", and "high rpm"just as much, it just happens to have a narrower rpm range than a typical gas engine.
Well, try running 2500 rpm in OD.
If you read the whole thread, you would have seen where I posted that towing either of 2 trailers that I tow (very tall 3800#, or a Rockwood too type at 6000# curb), I cruise in 5th, (technically OD) at 2200-2400 rpm from 65 to 70mph. A good wind puts me in 4th at 2800@65. Smooth as butter, and 4000rpm from redline. (No typo).
Climbing in my truck is done at higher rpm, up to 4500, where the horsepower is 240hp, same as the ED at max rpm. At that point, if I was to use all 300hp, I can drop a gear, or drive along side the ecodiesel, with him pulling 3600rpm. Big deal, $4000 more to save 900rpms? Not for me.... Think about that for a second, same hp, only 900rpm more....
Heck, my last bike cruised at 5000rpm, it didn't make me want to run out and buy a diesel, my sled cruises at 7000+...
