Full review

The Blue Ox Patriot 3 braking system is a proportional, supplemental braking device engineered for RV owners who tow a dinghy vehicle behind their motorhome. Designed to meet the legal requirements for towed vehicle braking in all fifty states, this self-contained unit mounts inside the towed car and uses an accelerometer to sense the motorhome's deceleration, then applies proportional braking force to the towed vehicle's own brake pedal. Unlike bulkier, permanently installed systems, the Patriot 3 is portable and can be moved between different towed vehicles, making it a practical choice for RVers who swap dinghies or want a braking solution that isn't tied to a single car.

Built with safety and simplicity in mind, the Patriot 3 features a straightforward setup that most RV owners can complete without professional installation, along with a clear digital display that shows system status, battery charge, and braking activity in real time. The system includes a breakaway switch to meet towing safety regulations, ensuring that if the towed vehicle becomes separated from the motorhome, the brakes engage automatically to bring it to a safe stop. Its proportional braking technology means the towed car brakes in sync with the motorhome, reducing wear on both vehicles' braking components and providing smoother, more controlled stops compared to systems that apply an all-or-nothing braking force.

For RV and camper enthusiasts who prioritize dependable towing performance, the Blue Ox Patriot 3 offers peace of mind on long hauls, mountain descents, and unpredictable highway traffic where sudden stops are a real possibility. The unit is compact enough to store in the towed vehicle without interfering with driver space, and its rechargeable battery system ensures it stays powered through extended trips. Backed by Blue Ox's reputation in the towing accessories market, the Patriot 3 is marketed as a reliable, user-friendly solution for anyone looking to tow a vehicle behind their RV while maintaining control, safety, and compliance with braking laws across different states.
