Top 7 Trailer Electronics and Monitoring Systems in the United States for 2025: Expert-Vetted Picks to Improve Safety, Compliance, and Animal Welfare

eRapta's ERT3 is the practical budget pick for simple backup and close-range monitoring of a horse trailer—the system is affordable, easy to install and widely available, making it ideal for owners who need a basic safety camera without extra bells and whistles. Financially it is the least expensive option on this list, though it trades off range, multi-camera support and some rugged features found in the Haloview and Voyager units.

TrailerHawk TH-700 Equine Monitor is positioned as the market leader for horse trailer temperature and environmental sensors thanks to an enterprise-grade sensor suite (temperature, humidity, CO2, tilt/shock and GPS) and nationwide cellular telemetry with predictive analytics. It commands a premium price but delivers lower long-term risk and detailed historical insights compared with simpler units on this list, making it a preferred choice for commercial haulers and competitive stables that prioritize data-driven animal welfare.

Pegasus PowerHitch is positioned as the best-in-class choice for horse trailer tracking because it combines a hitch-integrated power design with trailer-specific sensors, delivering continuous location, tilt and door-status telemetry tailored to equine transport. Compared with the other devices on this list it offers the easiest plug-and-play installation for trailers and lower long-term maintenance costs thanks to its powered operation and built‑in battery backup, making it especially attractive for frequent haulers who need reliable Horse Trailer Tracking and Telematics without recurring replacement battery expense. Its technical emphasis on trailer-specific alerts (load tilt, trailer disconnect) gives it an edge over general-purpose asset trackers when protecting horses and tack in transit.

The PressurePro Pulse FX is a market leader for professional-grade monitoring thanks to its rugged sensors, high-accuracy readings, and customizable alarm thresholds that appeal to commercial haulers and serious equine transporters. In comparison to the other products, PressurePro emphasizes durability and precision over consumer-oriented features, offering a longer sensor lifespan and proven reliability that can lower total cost of ownership for those who log many miles. For horse trailer owners who prioritize performance and minimal false alarms during long hauls, the Pulse FX is a top-tier investment.

The Tekonsha Prodigy P3 is widely regarded as the industry benchmark for horse trailer brake control thanks to its true proportional braking, intuitive digital display and robust diagnostic features. It holds its position by delivering smooth, trailer-speed-sensing braking that outperforms timed controllers like the Reese Brakeman IV for animal safety, while offering more consistent performance than wireless mobile options such as the CURT Echo. Although priced slightly above basic models, its long track record, strong aftermarket support and predictable performance make it a cost-effective choice for owners prioritizing reliable, repeatable stopping for horse hauling.

The Battle Born BB10012 100Ah LiFePO4 is a best-in-class choice for horse trailer owners who prioritize proven reliability, long cycle life, and simplified installation; its strong US reputation and robust warranty make it a premium but lower-risk investment compared with less-established cells. In a trailer system it delivers high usable capacity with far less weight than lead-acid and pairs exceptionally well with advanced inverter-chargers like the Victron MultiPlus-II or DC-DC chargers such as the REDARC, offering long-term total cost-of-ownership advantages versus larger-capacity but lower-cost alternatives like the Renogy 200Ah.
