A method for assembling a vehicle from a set of modules for travelling a planned route, wherein the set of modules comprises at least one functional module and a plurality of drive modules. Each drive module comprises a pair of wheels, electrical motor, and an interface releasably connectable to a corresponding interface on another module, wherein each drive module is configured to operate autonomously and has an individual set of energy parameters. The method comprising obtaining route information associated with route segments of the planned route, selecting a first drive module having an individual set of energy parameters matching route information associated with a first route segment and selecting a second drive module having an individual set of energy parameters matching route information associated with a second route segment, and thereafter commanding the drive modules to connect together and with a functional module.

A self-driven modular sandbagging device applicable to a dump-truck with a truck bed that defines a sand carrying volume, comprising: a replacing tailgate for the truck bed, capable of replacing the original regular tailgate of the dump-truck, at the lower inner end of the replacing tailgate an integral elongated housing is included, in free contact with the carrying volume of the truck bed, in the integral elongated housing an auger is rotatably installed; the auger is driven by a hydraulic motor located inside the housing, a hydraulic pump connected to the hydraulic motor is attached to the external side of the replacing tailgate, at one end of the housing a bag-filler nozzle is included.

A telescoping truck bed shell is disclosed herein. The truck bed shell is capable of being retracted so that the user can have full access to the truck bed and also extended so that the user can have a protected volume at the truck bed in order to store things. The telescoping truck bed has traversable frames and a traversable cover wherein the frames and cover may be traversed between extended and retracted positions depending on whether the truck bed shell is being deployed or stored.

A convertible trailer system includes a convertible trailer having a segmented lower deck, and a segmented upper deck mounted thereover. The segmented lower deck includes floating forward and rear belly ramps which are independently actuable relative to each other so as to be selectively raised and lowered relative to a pair of side rails which define the belly forward of the trailer wheels. When in a fully lowered position the belly ramps are lowered to a lower extremity between the pair of side rails so as to be substantially entirely below uppermost edges of the pair of side rails. When in an elevated position the belly ramps are elevated so as to be co-planar with or above the uppermost edges of the side rails whereby freight may be loaded laterally onto the belly ramps over the pair of side rails.
