Abstract

A wall extension apparatus is movably positioned on the upper end of a side dump body to increase the carrying capacity thereof. The extension apparatus may be pivotally moved from a transport position to either a first side dumping position to a second side dumping position. When in its transport position, the extension apparatus extends upwardly from the upper ends of the side dump body. Various embodiments of the invention are disclosed.
