Is that a timed based controller? IF so, there is a gue difference between the time based (applies full braking (which you have set power at) after the set time (which is adjustable) vs an inertia based controller. I used a time based for years, works fine. But then when we got our 2500HD, with the factory controller which is inertia based, I couldn't believe the difference! The inertia based controller will apply the trailer brakes based on the rate at which the tow vehicle is slowing down. Slam on the brakes and it will apply full power (that you have set it at), but if you gradually slow down and the controller applies a lower voltage to the trailer brakes. An inertia based will also release the trailer brakes once you have come to a complete stop, at least our factory controller does. Time based still applies brakes once stopped.
Had we not stepped up to the 2500HD, I would have bought the Prodigy P2 I think it was for our 1500.
