Same dealer used Class 8 retail truck sales fell 24% month over month in August, ACT Research reports, but the average retail sale price was up 2.2% to $64,367.
"The notable drop in used Class 8 sales this month is not necessarily a reflection of weaker demand, but more likely a result of tightening inventory," says Steve Tam, vice president at ACT.

Compared to 2025, retail sales were up 12% in August year over year and prices rose 11%, ACT's State of the Industry: U.S. Classes 3-8 Used Trucks report says.
"Dealers across the country are reporting that used truck inventory is increasingly hard to come by, and our analysis of multiple advertising sources confirms that available units are down meaningfully from earlier in the year. With new truck sales also running below last year's pace, fewer trades are making their way into the used market, supporting higher prices despite lower sales volumes," Tam added.
