The system includes one or more assemblies forcontrolling the air flow. The system is removably and adjustably connected to allow for compact storage as well as quick, easy, and lightweight installation and removal of the system from different trailers, containers, or cargo boxes, or the like.BACKGROUND

[0003] It is well known that improving the aerodynamics of a vehicle can improve vehicle performance (e.g., acceleration, fuel economy, wind noise, wear and tear on drivetrain components, etc.). This is believed to be particularly true in the case of relatively large and boxy vehicles, such as semi-trucks that typically pull generally rectangular trailers, containers, or cargo boxes. It is also believed that numerous products and concepts have tried to resolve this aerodynamic issue- but have not yet had much commercial success. Examples of known concepts can be found in a number of patents and patent publications, including US Patents: US4006932; US4741569; US9346496B2; US9637183B2; and US10227094B1 ; EP Patent EP1870320B1 ; and US Patent Publications US20140361579A1 ; US20150115651 A1 ; and US20160214660A1 , the contents of which are incorporated by reference herein in their entirety and for all purposes.

[0004] In evaluating the market and viewing presently known and commercially available products, it is believed that portability; versatility of the products to be used on different trailers, containers, or cargo box types; sizes and dimensions; and ease of installation and removal of said available products is lacking.
