I have the Blue Ox Patriot braking system and it works great. It also has a remote (wireless) sensor that will communicate with a display that mounts on the dash (plugs into lighter socket).
It lets you know when the system has problems (not a common occurrence). It sets up easy as well. I still haven't installed the break away cable (had some medical mobility issues), but that will happen before I hit the road again.
I use magnetic lights (on a 2013 Ford Edge) and that saves the hassle of diodes (there is also a wireless set of magnetic lights available but they are pricey). Also since the Patriot system pushes on your brake pedal, your normal brake lights come on as well (at least on my Edge), just some extra insurance.
I installed the base plate myself over a couple of days but it could easily be done in one day. The on-line videos (YouTube) and the Blue Ox documentation is fantastic. I also installed the one on my previous toad (Honda CRV). You need a good socket set, some steel drill bits and a good drill and a bit of patience as everything does not always line up.
Oh yeah, and a good set of nerves when taking off a frail looking large fascia and then having to make some mods on it!
OTH, a professional installation can cost you a day's labour at a body shop. My estimates ranged from $600 to $900.
I also wanted a Fusion Hybrid Energi, but got taken by the dealership with a bait and switch (should have walked
) and now only have the 2013 Fusion Hybrid as a daily driver. On the positive side, it can also be towed four down.
