No rpm rule there, eh? LMAO
Did I ever mention I didn't like the 6 speed for pulling? I think they are weaker than the 4500s.
40 hooks to my 5600... . Seems ok to me. Probably would have lasted forever if I would have switched tires for this pull. Greed and lazyness takes over though and tells you "you can break'em loose" "let'er eat" then BAM! and you think "I knew that was gonna happen!":-laf
who is the green and silver dually?
i've seen a before and after picture of that truck on myspace. he started with just the frame and cab of a red dually, and built that truck from it.
