To add to the confusion... I've only used the US Gear Unified brake system. Installed it on three different toads, and two motor homes. Once installed, there is no other item to connect or disconnect from the toad. No electrical lines, no air hoses, no nothing. Even better, most motor homes are already pre-wired for this system with an empty connector under the dash and connected at the other end to the 7-pin connector.
In addition it uses a small vacuum pump to provide vacuum for the toad's power brakes....ever tried to use power brakes on your car without the engine running?? Just think how much force is required for all those other braking systems that doesn't use the toad's power brakes.
Fully adjustable, monitor and controller right at your finger tips when driving the motor home.
Ok, I'm done.
