INDUSTRY’S FIRST EPA CERTIFIED SMARTWAY® TRAILER

Utility is unwavering in its commitment to be the most innovative trailer manufacturer. Reflecting this effort, the 4000D-X Composite™ was the first trailer to be EPA Certified SmartWay®. When you get a SmartWay® 4000D-X Composite™ (configured with proven fuel saving technologies) you not only get a light weight trailer that is built to outwork and outlast the competition, you also get a trailer that reduces emissions, increases fuel efficiency and improves the bottom line. These are true "win-win" benefits. Check out the EPA Certified SmartWay® 4000D-X Composite™ from Utility to find out how you can save some "green" and help the environment too.
