COLUMBUS, Ind. — Preliminary results from ACT Research indicate Class 8 commercial vehicle net orders climbed to 38,200 units in North America in April.

That’s a 158% increase from a year ago and the largest monthly order intake since March 2006, the company announced.

“Every cycle has one or two of those months when the breadth of participation rises and a confluence of events leads to these types of results. April happened to be that month this cycle,” said Kenny Vieth, president and senior analyst. “The list of positive drivers leading to the April order spike is long: Healthy freight, increasing trucker profits, pent-up replacement demand, rising used equipment prices, improving credit worthiness, rising prices for new vehicles, and lead times for new equipment that have pushed out to the end of the year. If that was not enough, there is the accelerated depreciation schedule for 2011 to consider. The challenge now is for the industry to translate all of this demand into trucks.”
