In combination with the bed of a pick-up, trailer or the like which is flanked by lateral walls terminated at their rear ends by a pair of tail-gate jamb elements forming two vertical post-mounting channels, an auxiliary dumping apparatus comprising: a framework consisting essentially of a pair of longitudinal tracks laid against said bed, a plurality of cross-members placed and dimensioned to keep said tracks in a parallel and spaced-apart relationship, one of said cross-members comprising one arm orthogonally and coplanarly located with respect to the longitudinal tracks along the rear edge of the bed between said jamb elements, a pair of upright members extending from the respective ends of said orthogonal arm alongside and commensurate with said jamb members, a pair of L-shaped fingers respectively secured to the upper ends of said upright members and shaped and dimensioned for engagement into the two post-mounting channels, and a pair of extensions at the respective ends of said orthogonal arm, said extensions projecting into the corners formed by the inner sides of said jamb elements and said lateral walls; a tiltable bin slidingly mounted on said tracks; means for locking said bin over the bed; means for moving the bin longitudinally along said tracks until the center of gravity of the bin is off said bed; and pivoting means transversally mounted at the rear end of said tracks for tilting the bin beyond the back end of the bed.
