Guys, this is great information. Let me just give you the run down on why I want one. My inlaws are into trucking. My brother own and operated a tri axle peterbilt, my father in law is a old truck driver, and my wife's uncle owns and operates a flat bed. (Pete) I have always kinda liked old macks since I was a kid. Anyway, I also like old tractors, and own an old International Farmall 666 I like to take to shows I own a old 1994 Dodge 2500 5 speed 12v Cummins. I do not enjoy driving a 3/4 ton truck eveyday. I have had thoughts about selling my 2500, and buying a 1/2 ton pickup to drive everyday. Then buying me a old B model Mack to eventually fix up, and pull my tractor's to shows.
