DRY VANS T TRAILER FOCUS: oday's dry vans are stronger than those of the past while often being lighter. Structural integrity has been improved due to more accurate methods in determining where stress loads are the highest, thanks primarily to better design tools that can analyze the properties of the various materials used in the construction process. By replacing heavier components with equally strong, lighter-weight materials and adding extra strength in areas that need beefing up, designers have been able to build significantly better trailers to carry specific loads without fatiguing certain design elements. Manufacturers also have reduced trailer weight by employing lighter, higher-strength materials in practically every area of the trailer, including the use of composite fl oors, which also increase load capacity. Another trend is composite pan- els used as side, front and rear door materials, which allow maximum interior width and length, and a smooth snag-free interior. Thinwall designs continue to gain popularity because they provide added interior width and cube capacity, which means more freight per trailer and better margins for fl eets. Many fl eets also spec anti-snag roof bows because they help prevent damage to cargo as it's being loaded. As durability and maintenance have become major issues for fl eets, trailer manufacturers have moved away from, or engineered alternatives to, traditional plywood liners.
