We’re pushing fuel efficiency to a higher level

Discover an even more fuel-efficient future

Utility’s light weight trailers are by design, more fuel-efficient. Our standard Utility Side Skirt and optional Utility Aerodynamic Tail further optimizes fuel-efficiency while improving trailer stability and reducing turbulence.




Utility Aerodynamic Tail

  • Streamlines airflow to diminish turbulence, and redirects heat away from the rear of the trailer to reduce heat convection and optimize thermal efficiency
  • Reduces low-pressure zone behind trailer, improving aerodynamic performance
  • Side assemblies automatically deploy and un-deploy with ease when swing doors are opened and closed
  • Roof fairing is engineered to not interfere with lock rods or rear light areas
  • Constructed of a UV-protected thermoplastic composite that promotes long-life
  • Weighing only 25 lb, it meets all DOT Photometric requirements

Utility Side Skirt

  • Directs air along the side of the trailer to reduce turbulence
  • Reduces aerodynamic drag from underneath the trailer
  • Built of UV-protected bi-directional Fiberglass Reinforced Plastic to extend skirt life
  • Engineered with a unique structural bend design at the bottom of the skirt for improved rigidity without a loss of flexibility
  • Retains its structural integrity when the trailer is moving at higher speeds
