I saw one once at the Flying J in Matthews, MO. Looked like a 4x4, but without the diff housing. Sat up kind of high; looked like 19. 5s. Didnt get to look at it closely, though. Seems like I saw the red "Cummins Turbo Diesel" under the Ram 4500. Also, stakesides, pulling a BP trailer, probably all loaded to the gills. Question: If they make them for the international market, why do they use the tired old "emissions" excuse? The Ford 450 and 550s have the same V10 or powerchoke as the smaller ones. Why couldnt DC put in the ISB and the V10? Just need heavier drivetrain, and maybe lower gearing options.
