Abstract: An auger support arrangement for attachment to a sidewall of a truck box enables the auger to be moved from a storage position alongside the sidewall to an operating position parallel to the tailgate and cooperating with an aperture in the tailgate. A separate hopper can be permanently attached to the tailgate with the auger having a flight which engages a drive coupling of polygonal shape of a drive motor attached to the hopper. The support includes an arm pivotally mounted on the sidewall with a swivel coupling on the free end of the arm. The arm allows the swivel to move from a position midway along the sidewall and at a mid height of the sidewall to a position at the top rear corner of the sidewall.
