D.P., if you look at the gear ratios Ford uses in their transmission, that most likely explains why they won the hill climbs with the 1 ton trucks. Kudos to Ford for building them that way. I don't know why Chevy and Dodge wouldn't gear theirs the same way. With six speeds, why not gear the first 4 gears for acceleration and pulling power, you always have 5th and 6th gears for fuel economy on the highway.
anyone else notice all the "heavy duty" trucks are still LT trucks?
as i clicked the link i was hopeing for a show down of F450,F550,F650 and similar trucks.
