Harvey,
I don't know - the integrated brake controller is supplied by Continental who provides advanced electronics to many OEMs. These include stability control systems, anti lock braking systems, etc. With the integration into the truck's CANbus system (transmission control module, exhaust brake function of the VGT), I suspect that the integrated trailer brake control is much more sophisticated than a simple Tekonsha Voyager or Prodigy (which I also have experience with and agree they're junk. )
Again, as I said, I have nothing at all against the BrakeSmart or MaxBrake (I may well wind up with the latter myself), but the 2012 ITBC seems to have addressed the obvious shortcoming of the earlier ITBCs. I'll reserve judgement until I see more first-hand reports; that's why I'd like to hear more first-hand experience from the 2012 purchasers. Hey, if they don't like it, they can always go to the MaxBrake.
