The other being the ability to maintain or gain speed to pass someone going up a hill. Being able to downshift from 5th to 3rd helps you get around cars faster than dropping from 5th to 4th and almost being at your redline.
I am with you on the fuel mileage though, depending on which psd it is. Bill hasn't mentioned it yet, but the reason why he is always towing 12k lbs to the scrap yard is because 8k lbs of it is his auxiliary fuel tank, 3k is his trailer and 1k is his actual load

And then subtract the $5-7,000 difference in purchase cost between the V10 and PSD of whichever year you're comparing and then see who wins!

So you think a Volkswagen Golf TDI would make a great tow vehicle simply because it's a diesel? Or one of the high strung diesels used in some racing applications over in Europe? Come on now, that's just ridiculous.
Heavy duty gasoline engines "PERIOD" are also made to work. Ford doesn't make a long stroke modular engine(except GT500) that's not made to work. In fact, there are many satisfied owners that have used their 5.4L and 6.8L to tow trailers for over 200,000 miles without any problems.
Quietness has nothing to do with capability. As I stated above my 6.4L is far quieter than a 7.3L engine and produces far more power. The new 6.7L PSD is more powerful and quieter still. In my previous career I had two trucks with a 14L Detroit Series 60 engine, and two trucks with a Caterpillar C15. The Cats had more power and were much quieter. Noise output has no bearing on power output!

i dont think that he is talking about power. just sound. i do agree with him. diesels shouldnt be quiet unless there in a jetta lol. i love the stink and sound. its very distinct. that being said i also love the sound of my 383 stroker in my 65. every car or truck to me has a distinct sound. a street rod should have the sound of a muscle gasser and big old work truck should chatter. but thats just me, not try to say that they have to have that sound. just what comes to mind one someone says they own a 69 olds 442 and when they say they tow it with a f350. two distict sounds come to my mind.

Diesel engines are design to convert fuel into horsepower, while gas engine convert about 70% of fuel into the heat.
High torque of diesel is just icing on the cake.
Have you guys hear the story about first civilian Hummers that were used on rallies in Baja? They used the more powerful gasoline engines in them, what made them running faster short distances.
But whole advantage was down the drain once they run out of fuel 10 miles before refueling stop.
On next rally they had diesels in them.

Okay, let's think of this another way.
Do you think your driveline would survive for very long if you were to shift like that frequently while towing?
Automatics are designed to shift under power, this is why we can do this all day long with as heavy a trailer as you please.

Well, its not. It was born the E4OD in 87 and become the 4R100 for 98 when it had some small upgrades done. Ford should have come out with a new 5 speed auto for the Super Duty, but they wanted to keep using outdated trannys to save money. If GM had not gone to the Alison, who knows how long we would have been stuck with the 4R100.
If you do PM me. I have never driven a SD newer than 01 or 02 and would love to drive one with the 6.4 and TS, along with leaf spring front end and all the other upgrades just to see what its like.

Already been done, and not surprisingly, the diesel did it the best. There is truly no denying that when it comes to heavy towing, turbo diesels are great at towing. But some people contend (I'm one of them) that the extra initial cost, coupled with higher maintenance costs and greater repair costs aren't enough to justify owning one. I am well aware of the fact they tow better, get better mileage and so on, but it only takes one $10,000 repair bill to wipe that out. I also am fully aware that most diesel trucks are trouble free, and even more so when they are maintained well. But a quick look through any of the diesel-specific threads on this forum will prove my point that IF a diesel breaks, it sure as heck ain't free to fix!

I don't like playing games I know I can't win.
I see your point. Thats only something I would do a few times. An automatic can be driven the same way daily and take it, and both my autos are.

Some guy in the 6.4 section had a bill for over $18,000 to rebuild it. It was something like a blown head gasket that let fluid leak into one of his cylinders and ruin a piston. How something like that could cost that much for an engine that had that few miles on it, I have no idea, but that was what he said. The only thing I thought "needed" fixing was the piston, a new set of rings, new gaskets and that was about it.
