Trailer net orders in May, at just over 16,000 units, slid 10% versus April, according to the most recent State of the Industry: U.S. Trailers published by ACT Research.

“While recent order volumes have been low and year-to-year comparisons appear weak, this is not indicative of current customer demand,” said Frank Maly, director–CV Transportation Analysis and Research at ACT. “Instead, the combination of the huge surge of orders late last year and a shortage of available build slots this year continues to dampen additional fleet order placement.”

Maly is quick to note that the low order volumes do not downgrade ACT’s forecast for the year.

“Freight volumes at advantageous rates will support fleets, and their investment plans will remain robust,” Maly said. “Our view that 2015 will be the best trailer market since the late 1990s remains unchanged.”
