This was a favorite among RV'ers when it was still available, its truly proportional since it connects to the brake pedal and senses the actual movement rather than using inertia switches or accelerometers, and doesn't require modifications to the vehicles brake system like other proportional systems do. Made in the USA, they stopped making it to release a new model, and just never got it to market.
