As any experienced tower knows, you aren’t always in the best situation to hitch a trailer when it needs to happen; sometimes you are in a muddy field, snow filled parking lot or worse. The attachments for the trailer brakes and lights are positioned below the rear bumper, in a very vulnerable spot on the Ford Heavy Duty.
Integrating these hook-ups into the bumper is a common feature with other brands, and seems like an easy thing that Ford could do to keep its customers from having to worry about getting their trailer hook-ups muddy, wet, or torn off. Also, it would be nice not to have to bend over so far.
