The f150 that I have has a heavy duty manual tranny out of an f250. 1st gear is a granny gear so it is great for getting going with a heavy load! The truck has the 4.9 straight 6 and runs pretty good. has 130k and still going, but the clutch is throw out bearing is kinda noisey (but its the ORIGINAL CLUTCH). When it goes, I'll replace it and keep on trucking! I am looking at 1 of the new Dodge Ram 3500 cab & chasis for 2007. I can't wait for the dealers to get them in!
