It's awarded to most trucks with a Ram logo and very few others! Lol

Medium duty trucks are those with GVWRs from 14001 to 26,000 pounds.

The Allison in the GM, the 6R140 in the Ford, and the Aisin in the Ram can all be had in medium duty vehicles. The only exception is the 68RFE, but this is mainly due to it not having a PTO provision like the others. People just like to throw the "medium duty" slang around because it makes them feel better about themselves.

I believe the RAM 6.7 is, I know the 5.9 was. Check at the TDR web site.

My Freightliner Business class M2 is a medium duty. It weighs 5.75 tons. Perhaps weight has something to do with it. The transmission looks bigger than my old 7.3PSD engine. All pickups, no matter how bad-ass they look, are light duty.

I don't know the hows or whys, that's just how they are designated. I'm sure google knows.

If it is used in a Class 4 to 7 vehicle, it is medium duty. Too many people throw that term around loosely.
