As I understand it, only the 03 Heavy Duties were available with the V10, but not many chose it because the Hemi is a more potent motor. I believe they were discontinued for the 04 model year. Sounds to me like they just had a few left over... I have only seen ONE myself however, very recently on the used lot of one of our local Dodge dealership. The V10 badge looked pretty cool, kinda carbon-fibery background. Very rare to find the new Gen Ram with the V10 though, good eye!!
