Not to say the V10 isn't a stout motor when towing, but any new diesel from the big 3 have 800+ tq and 350+ hp. That's twice the torque than the V10s. Theres really no comparison when loaded.
That's 800+ ft-lbs of torque on the diesel engine's crankshaft, but it's of course torque on the drive wheels that counts. You get that by using the proper gears to convert engine horsepower into the required final amount of torque at the drive wheels.
The turbo boost on modern diesel engines is what gives them a load pulling advantage at mountain altitudes over equal horsepower gas engines that aren't boosted - when comparing the same loads moved at the same speeds. It's too bad that modern big gas truck engines aren't boosted like the diesels are so that on grades - between the two types - you get equal pulling performance with equal horsepower.
FWIW, when I downshift our V10 and it's RPM makes a step function jump into the 4500-5000 range ... I feel a solid punch in the seatback as torque on the rear dullies leaps up.
