Abstract: Presented is a portable divider device for dividing the bed of a pickup truck into smaller compartments so that material, such as groceries, deposited in the smaller compartments do not spill all over the bed. The divider device is particularly applicable on trucks on which there is a camper shell of the type that encloses the entire truck bed, leaving only an access door at the rear of the truck which may be opened to place material to be carried in the back of the pickup bed near the tail-gate. The problem is that unless the grocery bags or other materials, are supported in some way, the first time the brakes are applied, the grocery bags fall forward and all of the groceries are scattered all over the truck bed. My divider provides a flat support plate that extends across the bed of the truck and abuts against the wheel well which projects into the bed of the truck.
