Bar‑M SS Series Straight Load Horse Trailers
The Bar‑M SS Series Straight Load Horse Trailers are designed for horse owners who value traditional straight-load hauling, durable aluminum construction, and practical features that make every trip safer and more convenient. Built for everything from weekend trail rides and horse shows to everyday hauling, the SS Series combines horse comfort, owner convenience, and dependable performance in a trailer that is built to work.
The SS Straight Load lineup offers multiple configurations to fit a variety of horse hauling needs. The SS-21-ST provides a traditional two-horse straight-load design with a front dressing room, making it an excellent choice for owners who prefer straightforward loading and unloading with ample storage space for tack and equipment. The SS-21-SR builds on that proven layout by adding a side ramp, allowing horses to walk forward out of the trailer rather than backing out, improving convenience and confidence for both horses and handlers. For those needing additional versatility, the SS-2+1-SR features a two-horse straight-load section combined with a spacious front box stall and dressing room, making it ideal for hauling larger horses, mares with foals, ponies, or horses that benefit from additional room during transport.
Every SS Straight Load model is built around a rugged all-aluminum frame, one-piece seamless aluminum roof, durable flooring system, and dependable running gear designed for years of reliable service. Inside, horse comfort and safety remain a top priority with HDPE wall liners, well-designed stall layouts, interior LED lighting, secure tie locations, and ventilation systems that help provide a comfortable travel environment.
Practical owner-focused features are found throughout the lineup. Spacious dressing rooms offer valuable storage for tack, feed, and equipment, while drop-down feed doors, escape doors, side-ramp options, rear-ramp access, and convenient walk-through designs enhance functionality and make handling horses easier at every stop.
Whether you prefer the simplicity of the SS-21-ST, the convenience of the SS-21-SR side-ramp model, or the added flexibility of the SS-2+1-SR box-stall configuration, the Bar‑M SS Series Straight Load Horse Trailers deliver the durability, versatility, and value horse owners expect from a trailer built to perform mile after mile.
