TRA Certification Inc.

Focused on eco-friendly, sustainable design, construction and operation, TRA, certifies that an RV manufacturer is "green capable" and uses their process, materials and components for a truly green assembly. TRA also verifies the green claims of materials and components suppliers.

During the certification process, the manufacturing facility, as well as the RV, are scrutinized against a checklist of items. In the factory, the manufacturing process and the materials used are evaluated. For the actual RV, the following categories are evaluated: Resource Efficiency, Energy Efficiency, Water Efficiency, Indoor Air Quality and Operation & Maintenance. Certification of the RV is offered at either Bronze, Silver, Gold or Emerald (highest) levels. Based in Elkhart, Ind., TRA Certification has been endorsed by the National RV Dealers Association.
