I cannot speak directly to the Dodge controller - I own a Ford with the factory controller.
I was not impressed with the Ford factory controller when I first used it as compared to the Prodigy P2 I was used to using I did some research and found out the system is actually quite different.
Again - this is for Ford, not sure how it works on Dodge vehicles. The basic input for the brake controller is not the pedal, or an inertia based system, but the vehicle ABS system which constantly monitors brake pressure (actual pressure, not pedal pressure) and wheel speed/spin. This translates into the brake effort that is sent to the trailer. The system is designed so that the trailer brakes are supplementary to the vehicle, not primary or independent, but tied together linearly. Also it is intended to avoid lock-up of the trailer brakes (again the ABS feed.)
This is very different than the system in the P2 which is pedal and inertia based. It increases brake effort in relation to the deceleration measured by the unit. In my case the primary difference was that when using a P2 I could set the trailer brakes to engage more forcefully, but with the Ford unit it is more proportional.
After pulling several thousand miles with both, I actually have come to appreciate the Ford unit. It is so seamless, very little jerking, surging, etc. However in aggressive braking situations that truly linear braking effort is much intuitive.
