TRAILER GUARDIAN KEEPS BOATS HITCHED UP
 "Montana-based Safety Products sent us a new accessory called Trailer Guardian that is designed to prevent decoupling while towing, as well as trailer theft, by locking the trailer coupler to the ball mount.
 
The company claims that this system prevents decoupling even when  the ball is smaller than the coupler, when the coupler is not locked  down or if the ball nut comes loose and falls off. We decided to find  out if these claims rang true.
 
We tested the Trailer Guardian with our Nissan Titan project truck. Installation was straightforward: First we removed the ball from the drawbar, then we fastened the Trailer Guardian to the drawbar using the ball mount and nut. Next, we coupled the trailer to the ball and adjusted the legs of the Trailer Guardian so that the "guard" was as close to the top of the coupler as possible, then we locked it in position.
 
To test the company's decoupling claim, we jacked up the tongue with a floor jack until the back of the truck began to lift, and tried to separate the ball from the unlocked coupler by jumping on the truck bumper. The Trailer Guardian prevented the coupler from detaching from the ball.
 
Next, we removed the ball nut and tried to separate the ball and coupler from the drawbar by driving the truck forward and back. The ball rocked on the drawbar each time we changed direction, but the Trailer Guardian prevented separation once again. Our rating: ****
