Abstract: A trailer for hauling and for delivery to a number of different delivery sites, automotive exhaust system parts, such as mufflers, pre-bent tail pipes and the like packed in large shipping containers, and, also, bundles of numerous straight tube lengths, is provided with a normally closed cabinet attached beneath its floor between its rear road wheels and its forward tractor connecting fifth wheel. The cabinet is divided into longitudinally elongated bins, each of about the same length as the straight tubes, for receiving and holding the bundles of straight tubes in longitudinal arrangement relative to the trailer axis. The sides of the bins are openable so that the tube bundles can be inserted and removed in a transverse direction relative to the trailer axis. A fork truck is releasably mounted upon the rear end of the trailer for use in unloading tube bundles in a transverse direction out of the bins at different delivery sites.
