Supplemental braking is becoming more and more common in today’s RVing world. It’s a good idea. Even a small SUV can weigh up to 3,000 lbs, and every pound counts. It’s good to know that extra weight of the vehicle in tow is not pushing you when you are trying to come to a quick stop, or even a moderate stop. It’s not only a good idea, it’s the law. All US states and every Canadian province have recreational towing laws.

At Trademasters, we are proud to be an exclusive Canadian dealer for Air Force One and Stay In Play Duo, SMI’s fabulously simple and easy to use braking systems.
