Thanks to the increased supply of late-model sleeper tractors, we are able to track the relative performance of 2012MY units with a high degree of confidence.

Diving right in, we see that the Peterbilt 386 dipped unexpectedly in July. Average mileage of 386’s sold was higher than the average by about 29%, which could account for some of the difference despite our mileage adjustment. All 2012 386’s reported sold in July were equipped with the PACCAR MX engine, which should not be responsible for the drop, but is worth noting. 

The Kenworth T660 and Freightliner Cascadia continue to perform similarly, with the T660’s 4% dip bringing that model very close to an unchanged Cascadia. The Cascadia continues to be the largest-volume 2012 truck sold by a large margin, making its pricing performance even more impressive.

Volvo’s 630/670 and 730/780 continue to perform similarly, with the 730/780’s higher mileage partly responsible for its result. 
The International ProStar ticked up in July, maintaining its position at roughly 24% below the average for this cohort.

Stay tuned for a look at how 4-year-old (2011MY) sleepers performed in the September edition of Guidelines, available later this week.
