We’ve been looking at the price difference between highway daycabs and their sleeper counterparts. The graph below shows the average retail selling price of both types of trucks going back two years, adjusted for mileage. We have also provided a graph showing average mileage for reference. We are looking strictly at four-year-old trucks here, so the periods in the graphs include the 2007 model year (1/2010-12/2010) and the 2008 model year (1/2011-12/2011).

As you can see, there is a clear premium for daycabs. This premium grew from an average of $6126 in 2010 to $7753 in 2011. Daycabs’ lower mileage is a factor, but the main culprit is lack of supply. As undersupplied as the used sleeper market is, the used daycab market is even more so. For example, there were 76% more sleeper tractors than daycabs in the population used in this study.

With OEM’s building more sleepers than daycabs, plus fleets moving towards more regionalized operations (thereby reducing need for large sleeper tractors), supply and demand are supporting high pricing. As with the sleeper market, don’t expect these factors to change much in the near future.
