I agree completely with Duke, a pressure sensing controller is the ONLY proper way to go.
Would you run air brakes in an "on/off" affair and think you could get smooth braking? Of course not, you need to modulate the trailer brake power to that of the tow vehicle. The only way to accurately do this is with a pressure sensing system. They are also not affected by grades, so you get consistant brake performance.
The only down side is that they cannot be trailer mounted for use with multiple controllerless tow vehicles.

I Support: Trailer brakes an every axle over the towing vehicle's GVW; CDLs for RVers; Safety inspections for ALL vehicles and 6 axle trucks (97K GVW proposal).
