The difference is even greater if you're talking about a truck with a pickup bed. In addition the diesels in pickups have a significantly larger power band. My sense is that 6 gears are more then enough for a 1 ton, especially in an automatic transmission.

I'd also point out that a lot of heavy trucks are going to 6spd transmissions. For example the cat on road trucks have a 6sp auto.
My C12 has a wider power band than say... A series 60 detroit. It's a dozer engine. It has to. That's why Cat can het away with fewer gears. It works off highway. Not on
