I believe all class I,II, and III (1/2 - 1 ton) trucks are considered light duty.
Class IV, V, VI, and VII (F-450 - F-750) are considered Meduium Duty.
Class VIII and higher (Kenworths, Western Stars) are Considered Heavy Duty.
I appologize for using truck terms in a pickup discussion.

Quote: The trucks are identical except for the higher torque and lower HP. The E350 Van with 255HP 5.4 V8 and 4.10's is rated at 13,000lb GCWR and the E350 with 215HP 7.3 PSD and 4.10's is rated at 20,000 lb GCWR. Imagine that, 7,000 lbs more tow rating with 40 less HP. ![eek [emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/eek.gif) Get off your high horse already.
We have been through this many times, Joe. If both vehicles are identically configured, then one powerplant will be favored over the other. The two engines have very different power characteristics and as a result require different drivetrains in order to have the installation optomized.

Stop beating around the bush, the higher HP rated 6.0 Suburban has a much lower tow rating than the lower HP 8.1 Suburban because of TORQUE.

And the engine in the Abrahms tank is rated to tow three times the amount your PSD is rated for and it develops half the torque your PSD does. So much for your torque argument.

Can I tow my 41 ft TT on I-95 with the Abrahms tank at 70 mph? What does that have to do with Tow Vehicles ?

We're not talking about TVs directly, just torque. You claim that one vehicle can tow more than another because it has more torque. I just provided a simple real world example of where that is not true by a long shot. If you want to change the gearing in the Abrahms, it will tow 5 of your little trailers at 70 mph without breaking a sweat.

Your right in your description here, and it makes my point even clearer. Starting with the 3/4 ton and going up the food chain of truck needs, diesel pretty much dominates the pack. Only the 1/2ton is without the option of a diesel, why is that? It is not necessary, as it was not designed to have the extra weight of the diesel over the front axle.
BTW - The diesel engine is more efficient than the gas engine at producing power from fuel. Sounds good to me.
Again, when you sell/trade your truck how will you recoupe your gas fuel vs. diesel enging comparison money ($5000)?

You just answered your own question: The reason that diesels dominate the large truck market is because they are cheaper to operate. Strickly an economic consideration, nothing else.
