Method and apparatus for an extendable logging trailer constructed of left and right main I-beam members having left and right male telescoping beams moving on rollers on the bottom inner flange of the main I-beam members. The male telescoping beams allow the trailer to be retractable or extendable so that it can assist in offloading the logs/pipes from the logging trailer. In operation, a front bolster and push rack are moved in unison by a first hydraulic cylinder toward the rear of the trailer at the same time as a rear bolster is moved by a second hydraulic cylinder toward the front of the trailer thereby causing the length of the trailer to shorten. As the trailer shortens, the logs/pipes which are carried on the bolsters are forced toward the rear of the trailer so that gravity eventually causes the rear ends of the logs/pipes to fall downwardly toward the ground which allows the operator of the tractor which is pulling the logging trailer to move the logging trailer forwardly causing the logs/pipes to become completely offloaded from the logging trailer.
