I bought a Trailer Guardian for my personal trailer. I work as a mechanic for lumber mill in the Kalispell, MT area. In the summer months we always have a 300 gallon water supply tank that is U.S. forest approved for fire prevention in the U.S. forest woods. I showed my boss the Trailer Guardian and he said let’s put it on the stinger. A Trailer Guardian was installed and the nut with the same ¾” air wrench to tighten ball in place.

The trailer was put on tow vehicle and the Trailer Guardian was secured to lowest possible setting and coupler chain hooked up also. After about 70 miles of towing down a major highway on forest service roads, a different noise was noticed, but the trailer was still following behind us.

When we went to take the trailer off the tow vehicle we noticed that the ball nut broke off at the base of the stinger. Thanks to the Trailer Guardian a major accident did not occur with lives saved and property loss avoided.

What a relief and peace of mind, safety and security that the Trailer Guardian can mean to those people towing a trailer from now on.

Thanks again Trailer Guardian.
