Used Class 8 retail volumes (same dealer sales) fell 8% month over month and 47% year over year in July, according to the latest preliminary release of the State of the Industry: U.S. Classes 3-8 Used Trucks report published by ACT Research.

Other data released in ACT Research’s preliminary report included month-over-month comparisons for July, which showed that the average retail price was flat, while average miles rose 1% and average age contracted 5% from June’s readings. Compared to July of 2021, the average retail price was 41% higher, with average miles and age greater by 2% and 9%, respectively.

“Given softer spot freight volumes and rates, coupled with still-expensive diesel fuel prices, the logical expectation was for continued declines in values,” Steve Tam, vice president at ACT Research, said. “However, we got a bit of a twist in the preliminary July used truck data where prices are concerned. Digging deeper may help explain the anomaly. The first thing to notice is the composition of units that were sold during the month. On average, the units were about five months younger, even though they have a few more miles on them.

“Occasionally, used truck data appear to be nonsensical. However, it is explained by a statistical phenomenon where the relationship between two variables in a population emerges, disappears or reverses when the population is divided into subpopulations. In the case of this month’s data, a higher number of higher dollar transactions resulted in improved overall results during the month.”
