Three to five year-old Class 8 sleeper tractors lost more of their value than anticipated in June, driven mainly by another large group of unusually low-priced 2012 Freightliner Cascadias and a large number of high-mileage 2014 trucks of various makes. On average, sleepers three to five years of age lost $5,089 (or 7.8%) from May to June. This pullback more than undoes May’s 3.9% bump over April, but basically just puts average depreciation back in line with our 3-4% monthly rule of thumb.

Not all models depreciated heavily. Models that were not heavily impacted by high volume or a high-mileage mix lost less than 3% month-over-month. Stay tuned for more detailed results by model early next week.
