Provided in this disclosure is a hoist for raising and mounting an interchangeable vehicle body onto a vehicle chassis. The hoist includes a hoist frame having a pivot end and an elevated end for slidably supporting the interchangeable body. A subframe with a bolt-on assembly is provided for fixedly connecting to the vehicle chassis. A linkage connects the hoist frame to the subframe. The linkage also includes a hinge joint member for raising the elevated end of the hoist frame. A mounting bracket pivotally connects to the pivot end of the hoist frame. The mounting bracket has a bolt-on assembly for fixedly connecting to the vehicle chassis. A winch assembly is retained in the elevated end of the hoist frame and extending to the pivot end for raising the interchangeable body onto the hoist frame.

A storage pod for use with a delivery vehicle is provided. The storage pod is configured to store packages and to dispense them when sufficiently close to a delivery location. Methods of delivering packages using a storage pod are provided.

A collapsible trunk for use with a vehicle having a wheel well. The trunk comprises a base wall and a side wall pivotally connected thereto. The side wall extends from the base wall and terminates at an upper edge. The side wall and base wall collectively define a storage cavity. The base wall and the side wall each have an expandable portion conformable to the wheel well in response to placement of the base wall and the side wall over the wheel well. The trunk is selectively transitional between a collapsed configuration and a deployed configuration. In the collapsed configuration, the base panels overlap each other, and in the deployed configuration, the plurality of base panels are co-planar to each other. The upper edge of the side wall moves away from the base wall as the trunk transitions from the collapsed configuration toward the deployed configuration.

A powered rail system is disclosed. The rail system is mountable on a truck bed, to which various accessories may be attached, and to which various electronic devices may be connected. The rail system includes first and second side rails, where the first and second side rails are substantially parallel and separated by a width, and where each side rail includes a front end, a back end, and a body extending between the front end and the back end. The rail system further includes a storage structure secured thereto, a first outside surface adjacent to the body of the first side rail, and a second outside surface adjacent to the body of the second side rail.

An article of manufacture for providing a rolling truck bed tray with a folding end is disclosed. The article includes a main tray component with a width that fits within the bed of a pickup truck, a folding extension component coupled to the main tray component by one or more hinges, and a plurality of casters coupled to an underside of the main tray component and the underside of the folding extension component. The folding extension component has an open position in which the main tray component and folding extension component are oriented at a common height above the bed of the pickup truck and a closed position in which the folding extension component is oriented on top of the main tray component.

A fleet for delivering packages comprising a first number of containers, each container comprising at least one compartment for receiving packages at a main distribution center. The container comprises a first attachment member on an outer surface and a second attachment member on an outer surface. The fleet comprises a second number of long-range transports, each long-range transport is configured to carry multiple containers from the main distribution center to an intermediate distribution center, each long-range transport comprising multiple first attachment receivers, whereby the multiple containers are attached to the long-range transports during transport from the main distribution center to the intermediate distribution center. The fleet comprises a third number of short-range tractors, each short-range tractor is configured to carry at least one container from the intermediate distribution center to delivery destinations for the packages in the container, each tractor comprising at least one second attachment receiver, whereby the at least one container is attached to the short-range tractor during transport from the intermediate distribution center to the delivery destinations and back to the intermediate distribution center. The third number is at least twice as large as the second number and wherein the first number is at least twice as large as the third number.

Provided in this disclosure is a hoist for raising and mounting an interchangeable vehicle body onto a vehicle chassis. The hoist includes a hoist frame having a pivot end and an elevated end for slidably supporting the interchangeable body. A subframe with a bolt-on assembly is provided for fixedly connecting to the vehicle chassis. A linkage connects the hoist frame to the subframe. The linkage also includes a hinge joint member for raising the elevated end of the hoist frame. A hinge assembly pivotally connects to the pivot end of the hoist frame. The hinge assembly has a bolt-on mounting bracket for fixedly connecting to the vehicle chassis. A winch assembly is retained in the elevated end of the hoist frame and extending beyond the pivot end for raising the interchangeable body onto the hoist frame.

A loading/unloading system for an associated truck bed includes first and second laterally spaced rails configured for re) receipt in the associated truck bed. First and second support leg assemblies are operatively associated with the first and second rails, respectively. First and second motors are received on the first and second leg assemblies, respectively, and are configured to selectively raise and lower the first and second rails. A sensor assembly is mounted on the rails to monitor the position of the first rail relative to the second rail. The sensor assembly is interconnected to the first and second motors for maintaining the rails at the same height relative to one another.

A storage arrangement that includes a rack receiving space; and a movement space. The rack receiving space includes at least One movable rack and the movement space may contain a movement device that interacts with the at least one rack. The movement space is arranged above the rack receiving space in a direction of gravity, and the movement device is releasably engaged with the at least one rack.
