Abstract: A modular trailer wall system for containing loads. The trailer system is detachably attached to a deck of a utility trailer, the deck and wall system being adapted to be towed by a vehicle. The wall system has two side walls extending upwardly from the pair of lateral edges of the deck. A front wall extends upwardly from the leading edge of the deck. A removable, adjustably located partition extends upwardly from the deck. The removable partition is adapted to extend between the two side walls at a position that lies above or ahead of the trailing edge of the deck. Locking mechanisms detachably attach the removable partition in its upright position to one or more of the side walls. Attachment mechanisms detachably secure the wall system to the deck.
