I thought that the letter after the numbers only represented the "trim" level throughout JD' green equipment.

The letter is the "option" level. Sort of like the difference between a Chevy 1500 W/T and a Silverado.

That's how I understand it. 
There was some discussion above about transmissions and iirc, axles being different with an "R" that had me questioning myself.

That is true though. It's not trim... It's mechanic differences. The W/T came as a 4.3L with a manual... Not the Silverado.
The JD units have completely different specs between the E and R models.
Maybe I used a bad example. But the letters on the JD models indicates more than "trim". It's mechanical.
