Supplemental braking systems are a key part of any flat towing set up so you definitely want one that will work best for your 2014 Ford F-150. One of the preferred systems for our installers and what I recommend is the Stay-IN-Play DUO proportional system, # SM99251. It will apply the truck brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

Installing the DUO is definitely more involved than a portable system but once the initial install is over with you just flip a switch to set it up when you're ready to tow.

With any system keep in mind that the # RM-88400 relay is required to prevent the towed vehicle's brake signal from overriding the turn signal from the RV when applying the brakes during a turn. (The RM-88400 relay is not required when using magnetic tow lights.)

Be sure to consult your vehicle owners manual for specific information on flat towing the vehicle. I have also included some helpful links to our series of help articles on flat towing for you.
