Nah... QTI and Durango are simple old style open light truck transfer cases. Functionally a open diff in the middle and open diffs on each axle (there is just a little rear bias because of the way the gears are designed). They depend entirely on brake traction control to stop wheel spin. These are what some of us call AWD systems. The complexity of axle disconnects (e.g. slip clutches) are added to other more car like vehicles to save some mpg. These are typically not strong enough for light truck applications, light trucks have more significant things that affect mpg. The mpg improvement of an axle disconnect is probably in the noise.
The QTII, on the other hand, has clutches within the transfer case, so it can run in completely open to completely locked depending on the whims of the traction computer. This is a true 4x4 case.
