Silver Eagle designs, manufactures and markets several lines of truck and trailer products that lead the transportation industry in performance and dependability. Silver Eagle designed this trailer and continues to manufacture it at its Portland Oregon facility at a rate of over 250/year. The monocoque design of this trailer is where the chassis as a whole is made by separately formed steel/aluminum panels which are welded together to form a unit. This trailer is one of many products that Silver Eagle manufacturers for UPS. Silver Eagle partners with UPS in its mission to deliver more (24.7 million packages per day) with less environmental impact.

Hot-dip galvanizing was specified by UPS for the chassis of these trailers for corrosion protection. This is in keeping with UPS's commitment to help build safer, stronger and more resilient communities which are supported by a healthy, sustainable global environment. As pointed out by the AGA, "sustainability is intrinsic to hot-dip galvanized steel" and "it is a proven steel corrosion system that transcends time with minimal economic or environmental impact."
