From the way i see it, my 5.8 is like a rocket compared to my grandpa's 1886 F250 deisel. (non turbo) 6.9? I dont remember exactly. But the point is, even though that thing had very little acceleration (it was slower than sh*t), just from the way it drove you know you could pull the foundation out from under your house.
Diesels are great for towing because the make exceptional power at very low rpm. Thats what you want to get your load moving without having to rev to 3 or 4 grand.
And i believe if you do the math, even though deisel is more expensive than gas, the better fuel milage does pay itself off (at least in my area). Plus from what ive heard, you can put large trailers on the deisel trucks and its like you dont even feel them compared to gas. And they dont drop the milage once the trailer is on there like a gas engine will.
Basically in every way i see it the deisel is better than the big V-10.

I'll buy that it is a higher torque motor, I have no doubts that it can pull some incredible stuff. The only thing I'd continue to disagree with you is that the 460 has its power at lower RPM's. I'd need to see dyno's of the 460, the new 5.4 produces over 80% of its torque curve at 1000 RPM or something sick like that (I remember the commercial, but I forgot the exact RPM). But being that the 460 produces much more torque it is probable that it still produces much better at the low ranges.

Alright... Here is where I am in this quest for a truck...
I test drove a F-350 4X4 Lariat V10 Duelly tonight. I thought my wife would hate it and she test drove it as well. Turns out she liked it and did pretty good parking in a lot and driving in some narrow streets we have locally... So this might work.
Now the technical questions:
Apparently it had a transmission replaced 2 years ago. I don't think it pulled much but was used to haul tools around.
What should I look for? Is it possible to spot the V10 plug issues?
Oh, it's a 1999 with 200,000 km's asking $15,000 CDN. I think I can get if for $13,000 (I offered $12,000 and I wasn't blown off). Body is in great shape and the leather is clean and remarkably good (better than my 1994 Probe with 117,000 km's).
Are there any "Gotcha's"?

Sounds like a nice truck. Having the trans replaced might concern me a little, though. Why did it go out? Was it repaired properly? Aside from that I don't see anything against it. If I bought a new truck I'd look into a V-10, they are good tow vehicles. Compared to the 7.3 diesel, they will get the job done just as well, but tend to work harder to do it. Good luck!

The replacement for displacement = Technology
A poorly designed large engine vs a well designed and modern engine.
The new 3v 5.4 is an amazing engine it is designed for lighter duty than the V10.
Overall the 5.4 doesnt produce as much torgue but it offers torque right when u need it. It is a superior motor in almost every way when compared to the 460.
Dont forget the reason we have smaller displacement engines today is because the new smaller engines are stronger lighter more powerful and most importantly more efficent.
You really cant compare them they are apples to oranges.
