Upstaging all these routine measures is the new TowCommand system, a feature we feel is a must-have for drivers who tow. Gone is the light switch-like, on/off, all-or-nothing braking prevalent in aftermarket trailer brake fitments, that makes stopping on a dime difficult. With TowCommand, touch the brake pedal, whether on the flat or on a grade, and the trailer begins slowing, exerting a mild drag on the Super Duty's forward progress. Press harder on the brakes, and the trailer's drag increases. Release the brakes, and the drag fades. As the Super Duty comes to a stop, the trailer brakes gradually back off, virtually in sync with the towing truck. No jerking. No yanking. Its operation is truly proportional to the amount of brake pressure. In back-to-back testing with an 11,000-pound trailer, we were able to stop precisely where we wanted from 25 mph and 45 mph with the new system. Conversely, when using an aftermarket system, we were not able to accurately stop; we usually stopped short of the mark and had to release the brake and creep up to position. This makes the system more comfortable and less annoying for driver and passengers, and less annoying to the motorists behind you. The system enhances safety as well; it gives audible and visual warnings if the trailer wiring becomes disconnected. It's also tied into the truck's anti-lock brake system and uses a special trailer brake strategy when the ABS detects poor traction (wet pavement, for example). No aftermarket trailer brake controller can do this. Next Page
