The December total is an increase of 115 percent compared to December of 2009.
"The industry closed 2010 with a string of three strong months of net orders. With nearly 71,000 orders booked, the fourth quarter was the best quarter for Class 8 vehicles since the second quarter of 2006," said Kenny Vieth, president and senior analyst. "The ramp-up in demand is consistent with the upcycle we have been forecasting for over a year and confirms production levels will increase significantly in 2011."
Preliminary net order numbers are subject to revision and are typically accurate to within 5 percent plus or minus.
