SL1400 AR

Renn pups are designed and manufactured in Alberta to meet the needs of the most hard core gravel hauler. With a Renn gravel pup trailer behind your truck, you increase your payload every trip, which at the end of the day, puts more money in your pocket.

A heavy duty wide-flange I-beam creates a strong durable frame that withstands the roughest haul roads. Renn pups come with fourteen-foot (tandem axle) or seventeen-foot (triple axle) boxes and are available with spring or air-ride suspensions and many other options such as lift axles.

All Renn pup boxes and frames are shot blasted, zinc primed and coated with PPG urethane paint, using a state of the art paint process to ensure long-lasting protection.

The wiring is fully enclosed and utilizes a modular wiring harness that protects against moisture, corrosion and damage.

Renn pup trailers are your best choice for long lasting quality and performance every time.
