I also wonder how it supposedly knows when you are going down hill and not braking. Are there adjustments for vehicle size?
IIRC there are adjustments to control how much toad braking is applied. As far as going downhill and not braking, it doesn't really matter. The brakes on the toad activate when the toad pushes against the tow vehicle. When going down hill and not braking, the speed between the two vehicles is equalized, and as long as the tow vehicle is not slowing down, the brakes on the toad aren't activated. It's very similar to surge brakes on trailers.
