Sales volume and prices of used Class 8 trucks were substantially down in November, according to ACT Research.

The price of the average used Class 8 vehicle in October skidded, as did estimated industry sales, with each falling 19% compared with a year earlier, ACT Research reported.

At a time of slowing freight volume and an increasingly adequate supply of power units, the average used Class 8 truck still brought a higher sales price in June than in the same month a year earlier, according to ACT Research.

The average used Class 8 brought a sharply higher sales price in April, even as inventories appear to be building, ACT Research reported. The average price was $48,532, up 15% compared with $42,100 a year earlier.
