It is worth noting that I believe MDS will only be on in 0 torque situations (flat surfaces, ie. not pulling a grade, little-no acceleration). Admittedly, I don't have a way to describe it better than that, although 0 torque may not be the appropriate term.
It almost seems to particular, Dodge should offer three settings for all MDS equipped models:

Eco - finds the tallest gear faster and keeps MDS longer (over slight grades, idles when warm in MDS and accelerates in MDS under slight throttle application such as driving at low speeds in a parking lot.

Normal - Which is the current application we now know. MDS activates only during constant speed, slowing down, etc

Tow Haul - Same Tow Haul setting we know now (late shift changes, etc)
