Comprehensive list of historical truck and trailer production figures

Nov. 27, 2018
An archive of annual trailer manufacturing statistics from back issues of Trailer/Body Builders magazine spanning 1975 through 1999.

Wading through truck and trailer production statistics is a tricky business. Who’s providing these numbers, are they sales quotes or actual orders, what trailers are we counting, so on and so forth. And above all else – what exactly do they mean?

Even a seasoned journalist like long-term Trailer/Body Builders editor Paul Schenck – who dedicated his entire career to covering trailer and truck body manufacturers – needed to conduct in-depth research to make sense of the annual sales figures, and several pages to explain their relevance to readers.

In other words, making actionable sense of gobs of figures requires the skills of a patient professional, and the considerable resources of a publication that takes pride in being the only magazine for people who produce and sell commercial truck bodies, trailers and truck equipment.

Fortunately, Trailer/Body Builders magazine, which has analyzed truck and trailer statistics for more than 60 years, is here to help. Our Truck-tistics archive, which dates to November 1975, preserves decades of production reporting by Schenck and others – much of it previously found only in print – making the information quick and easy to use for today’s manufacturing executives.

Inception | Trailer production starts the long climb up again (pdf) November 1975

Statistical analyses of truck and trailer production didn’t originate in 1975, to be sure. Manufacturers, and their sales and marketing managers, have attempted to crunch the numbers, and create accurate forecasts for future production, since the first semi-truck was built more than 100 years ago.

But that year did give us the first “The Alcoa Forecast of Trends in the Truck Trailer Industry,” presented at the 1975 Truck Trailer Manufacturers Association board meeting by then-Alcoa Market analyst William Clingler, which spurred Trailer/Body Builders’ efforts to dive deeper into the available reports, including the one then produced by the US Department of Commerce’s Census Bureau, and form more accurate predictions about truck and trailers sales in the future.

Clingler, according to Schenck’s November 1975 story “Trailer Production Starts the Long Climb Up Again,” investigated dozens of market indicators while trying to determine which ones were most effectively correlated with truck trailer production, and which ones were most useful for predicting trends.

Alcoa’s formula was based on the Federal Reserve Board Production Index and the Fixed Investment Index, which is a measure of the nation’s total expenditures on structures, residential and non-residential, and equipment, such as trucks and trailers.

The company’s work was well-received by trailer manufacturers, so it offered to update its forecast annually, and Trailer/Body Builders vowed to ramp up its reporting by publishing much of the information monthly in a new statistical “Truck-tistics” review page starting in December, 1975, including Alcoa’s forecast, the Census Bureau’s truck trailer shipment report, the monthly truck tonnage report from the American Trucking Associations (ATA), and automobile manufacturer’s retail truck sales and stocks.

Trailer/Body Builders followed up on its promise to deliver improved forecasting in December 1975, drawing on truck production, the ATA’s intercity freight tonnage index and the leading indicators from the Alcoa Forecast to paint a more complete picture of where the trailer market was heading.

The new section, however, was not yet branded as Truck-tistics, instead going by the more mundane moniker “Industry Data.”

Initial iteration | Trailer production jumps 37% (pdf) January 1976

Truck-tistics, officially, is here.

The new section, using leading indicators to forecast trailer production, debuted in January, 1976, and continued to appear monthly in the pages of Trailer/Body Builders magazine for the next 25 years.

The first report noticed the successful use of ATA’s Index of Motor Freight Tonnage, the Federal Reserve Board Production Index and the Fixed Investment portion of the GNP, which accurately predicted an upward trend in trailer production, with shipments jumping sharply from September to October.

Annual inspection | 1976-2000

Trailer/Body Builders delivered its first annual review of yearly trailer production in March, 1976, looking back at a dismal 1975 in which the number of trailers built was slashed by more than half, year over year.

The roundup featured a breakdown of trailers produced by form—from complete “wheeled units” to container chassis, dollies and converter gear—and function, including van, reefer and tank trailers. It also included a summary of heavy-truck sales and brief look at the most recent leading indicators.

Compiled below are links to scans of the original annual reviews. Occasionally the preliminary figures released early in the year were revised. In those instances, a second article was published mid-year.
