Medium duty demand ended 2012 on a strong note.

This updated status of the North America commercial vehicle market was included in the State of the Industry report, recently released by ACT Research Co. The report covers Class 5 through 8 vehicles for the North American market.

"The last time Classes 5-7 net orders were as high as they were in Q4 was in Q1'08," said Kenny Vieth, ACT's president & senior analyst.

"Strength was broad-based throughout trucks, buses, RVs, and step vans. As for Class 8, orders above the level of build allowed the backlog to rise for a third consecutive month in December," he added.
