Abstract:
1. A method of collapsing an extensible trailer, comprising the steps of: setting a trailer brake on the trailer's tires to secure a rear frame stationary; removing pins for a front cargo deck on a forward end thereof; pulling and securing in an unlocked position a frame pin release operator for releasing a front frame from the rear frame; using a tow vehicle to pull the front frame forward, thereby separating the front cargo deck from a rear cargo deck; raising the front cargo deck; backing the tow vehicle until the front and rear frames are collapsed; sliding the front cargo deck over the rear cargo deck; returning the frame pin release operator to the locked position; replacing the pins for the front cargo deck; and backing the tow vehicle into the trailer thus, thereby engaging the frame locking pins.
