Tired of being held back by bad airflow over your trailer? The large
endplates of the Aerotravel III are designed to trap oncoming air, while
louvers assist airflow under the wing and reduce vacuum and turbulence
to reduce drag and increase fuel economy, according to the manufacturer.
Both the primary wing body and the mini secondary wing are adjustable.
The Aerotravel III is a clip-on system with no drilling required.
