My coach came with Brakemaster installed in the coach approximately a year and a half ago.(If that means anything). I was told I only need a second vehicle kit to put in my toad. When I look at what comes in a second vehicle kit it only looks like wiring items. Wouldn't I need an air cylinder in the car? The local company that installed my towbar setup was telling me it would be practically the same price to just install another system(I am not sure they know what they are talking about).
