Patriot II supplemental brake system
I've watched every video possible about the Blue Ox Patriot II braking system and not one tells you how it "really" works. It's simple enough but what I'm trying to figure out is how does it know to proportionately apply the towed vehicles brakes when there is no physical connection to the motorhomes brakes? Does the control module on the RV dash know that you're applying the brakes?
