Abstract
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.
