Product Features
Two Full-Height Side Access Doors
Features two full-height side access doors, one on each side of the trailer. Each door is equipped with a full-height cam latch for secure, easy operation, providing maximum convenience for loading and handling livestock.
Over 50 Years of Sundowner Excellence
Built by Sundowner, a name synonymous with quality livestock trailers for over half a century. This heritage is built into every detail, from the solid 4-inch I-beam frame to the durable pre-painted aluminum skin, ensuring a trailer that lasts.
All-Aluminum Construction
Constructed with a lightweight yet strong all-aluminum design. The interlocking extruded aluminum floor and pre-painted aluminum skin provide long-lasting durability and resistance to rust, while keeping weight down for more efficient towing.
Swinging Center Gate & Calf Gate System
Configure your trailer with the gates you need. The 16' model comes standard with a swinging center gate—also available on 12' and 14' models—for creating separate compartments. The rear features a main gate with a built-in sliding calf gate, providing flexible options for handling animals of all sizes safely.
Spacious 6'9" Wide, 6'6" Tall Interior
Designed with a roomy 6-foot-9-inch width and a 6-foot-6-inch interior height. This generous space provides ample room for livestock to travel comfortably and safely, reducing stress during transport.
Safety & Reliability
Designed with safety at the forefront. It features a breakaway braking system, two safety chains with clevis hooks, full LED lighting, and rubber torsion axles for a stable, controlled ride, providing peace of mind every time you haul.
