XTRA Lease, a provider of semi-trailer rentals and leases, has ordered more than 2,000 new trailers for 2013, including a mix of dry vans, reefers, flatbeds, chassis, and liftgated van trailers.

Dry vans and reefers will receive fuel-saving aerodynamic side skirts and low-rolling resistance tires. All vans also will receive trailer tracking units to help fleets attack utilization and costs.

Since 2010, XTRA Lease has invested heavily in new trailer orders, adding nearly 30,000 new trailers in the past 3 1/2 years.

In addition, XTRA Lease is retrofitting hundreds of 2010 model-year trailers in California with side skirts, making them compliant with the California Air Resource Board’s Greenhouse Gas requirements. Combined with the new recent purchases, XTRA Lease is believed to have the largest fleet of skirted trailers in the U.S. at more than 20,000 trailers.
