An auxiliary dolly attachable to or integral with the rear of a primary trailer includes a first portion attachable to or integral with the primary trailer, a second portion comprising one or more axles with wheels, and a pivot point at which the first portion is coupled to and movable relative to the second portion, and further includes one or more cylinders configured to adjust the first and second portions relative to each other and apportion weight between the primary trailer and the auxiliary dolly. At least one or more booster axle groups and one or more trailer axle groups are configured to shift independently. This allows for efficient and cost-effective load balancing.

A quick connect logistics trailer used with a forked vehicle, where the trailer includes two movable fork guides to attach to the forks of the forked vehicle, a fork guide spacer to move the fork guides to accommodate different fork spacing, and a movable top platform attached by hinges to allow access to components under the top platform. The quick connect logistics trailer also includes side mounted fork pockets to lift the logistics trailer. The quick connect logistics trailer also includes two linear latches attached to the fork guides that can be attached to the forks of the vehicle, and two switchable magnets attached to each fork guide to attach the fork guides to the forks. The quick connect logistics trailer can also include a trailer clip attached to the trailer and a fork truck clip assembly attached to the forked vehicle, where the trailer clip assembly temporarily but securely attaches to the fork truck clip assembly to allow the forked vehicle to tow the logistics trailer.

A modular slave vehicle articulatable at one end thereof to another slave vehicle and at another end thereof to an independently driven master vehicle, simultaneously. The slave vehicle comprising a body including a driving system; a structural frame supporting said body; a master coupling system in the form of a mechanical stress absorbing coupling mechanism; at least one first slave coupling device; at least one second slave coupling device; said first and second coupling devices, when mounted to two adjacent slave vehicles intended to be articulated to each other, are detachably connectable to each other to form a tandem coupling configured to constrain all DOF therebetween.
