The intelligent BackTracker trailer steering maintains trailer-to-vehicle alignment during backing to avoid jack-knifing. Steering control algorithms enhance high-speed stability allowing reduced trailer and tongue length. Small, light, and short for easy towing, parking, hookup, and storage. Manual start/stop control is available from inside the vehicle
