This table is part of the North American Trailer Output Report published each year by Trailer|Body Builders. It shows the 2004 production figures for the largest trailer manufacturers. Read the related feature article, "Trailer production up 31% in 2004", which includes details and insights from each company interviewed this year. This annual survey is made by contacting a member of the management team at the manufacturing company. The ranking of the companies does not necessarily reflect their relative success in terms of profitability or revenue received, but only the number of trailers produced.

* Estimate = If a company declined to report their figures it is noted on this table. A good-faith estimate has been included here to help preserve the approximate accuracy of the total manufacturing numbers for top producers. This allows for a general comparison of changes in annual production from year to year.

Also: = Not among the top producers, but noteworthy production.

Note: Percentages shown in this table have been rounded to the nearest whole number.
