Utility’s new Aerodynamic Tail comes as a factory installed standard specification on Utility’s dry vans and refrigerated trailers with rear swing doors to facilitate lower fuel consumption and reduce aerodynamic drag. The tail is manufactured with a UV-protected thermostatic composite material and is made up of two full-height side fairings and one full-width roof fairing. Connected to the rear doors, the side fairings employ automatically when the doors are closed and return to position when opened. The roof fairing will not interfere with locking rods or lighting. Best of all, the product comes in at a svelte 25 pounds.
