The result has been significantly better trailers that can carry specific loads without fatiguing certain design elements. Structural integrity has been enhanced because of more accurate methods in determining where stress loads are the highest. Improved design tools can better analyze the properties of the materials used on the assembly line. Trailer manufacturers also have reduced weight and increased load capacity by using composite floors. Composite panels used as side, front and rear door materials maximize interior dimensions while providing a snag-free surface. Thinwall designs also provide added cube capacity. Many buyers also spec anti-snag roof bows that are less likely to dam- age cubed-out cargo while it's being loaded. To improve durability and reduce maintenance, trailer manufac- turers have engineered alternatives to traditional plywood liners. Following is a sample of trailers and their specs from six manufac- turers. For other models and more detailed specs, visit the manufactur- ers' websites.
