I'm pretty sure that the Dmax is only in first gear. I'm pretty sure that the pre 2013 Rams were in gears 1-3. Not sure if that changed for MY 2013. I can't recall what ford does, but I know they have it.

Since they all use similarly rated axles, they all have to have some form of it to keep parts from breaking.

Nobody can say for certain just how much power that TQ management takes away. So the comparisons are impossible/meaningless.

I would be interest in the math at highway speeds. This is what will keep the load moving up the hill with/without downshifting and/or how much it does.
TQ management is not in effect at these speeds, so the math will be accurate

Even though the torque out put may be limited in the new trucks it is still extreme what they are capable of. I use these trucks for very heavy loads and at times in very soft ground. I have witnessed an 03 Duramax moan and groan until it finally spins out trying to move one of my trailers in soft ground. At that point I hooked the new Ford onto the same trailer and placed the transfer case in four low and the transmission into drive. The result was unbelievable. Removing my foot from the brake and very lightly touching the throttle was all that was required to move that 32,000 lb trailer through the soft ground.

You bring up a good point. Since I know that the Dmax has had TQ management since 2001...It is possible that the 4x4s could be programed a little more aggressively since some of the power is going to the front axle. I doubt that was the case in the early Dmaxes as it was in it's infancy. And it may or may not be so today...But computers have come a long way since then, so it is likely.
