With all of our August data received, we have determined that the average sleeper tractor retailed in August sold for $50,767 and had 537,540 miles. This figure beats July’s record by $700, and is higher than last August by $2414 or 4.8%.

Average mileage has remained relatively steady in the 535-555,000 range since November, 2011, so the price increases of the past two months are notable.

Even four-year-old sleepers, which had been depreciating since May, headed back up in August with a $1098 increase over July to end up at $67,046 on average. This figure is lower than last August by $1422 or 2.1%. August’s average mileage was 434,956, which is 10,877 lower than July and 22,203 lower than last August.

So the sleeper market is still showing considerable strength, but the newest model years are no longer driving increases in the averages. Demand for trucks with under 600,000 miles will continue to support high pricing.

Stay tuned for more detailed analysis early next week in the October edition of GuideLines.
