I'm seeing things back and forth on these trucks...........4200, 4300, 4400 etc...... 4200 I see with the smaller engine.......so no thanks 4300 & 4400 I see the DT466 in the 4400 as well as the 4300 + the 500 series engine and GVW back and forth......what is really the difference between the two trucks? Besides getting the right truck I need it to be 2002 or newer....modern look. Yes is cosmetics but its what I want and the image I wish to present. Many of you have helped me with info on various trucks and I thank you. From what I've gathered International is the most friendly and problem free with the DT466. I like the idea of being able to easily rebuild the engine if need be without removing it from the truck nor trashing it for a new one like CAT due to not being sleeved. I think International is the way I am going to want to go though I am still keeping my options open. Once I get a truck I'll do my best to picture document as much of the process as I can for everybody from start to finish.
