The exterior aerodynamics played a significant role in the design of the L1 trailer. Reducing The Frontal Area. One of the key ways to reduce aerodynamic drag of an object is to minimise the frontal area. Travel trailers are typically large, tall boxes, so shrinking the frontal area presented a good opportunity for aerodynamic improvement.
