Amen on the V6 decision...I think Ford decision-makers would be surprised at how much demand there is for a good mileage diesel in a F150. I have talked to several contractors around here who have to buy heavy duty trucks just to get a diesel engine...who really want a half-ton. I think they would be overwhelmed with the response...especially with the gas prices at over $1.50 per gallon and unlikely to drop much. I too, have thought about putting a different engine in a truck, but thought about the opposite...putting a diesel engine in my 2000 F150. In my state, I don't have emissions tests, so I wouldn't have to worry about that...just making it all work right with the computers, sensors and the like.
