Abstract A carrier attachment conformed to engage the trailer hitch tail stock of a motor vehicle includes a tube segment supporting an electrical motor at the upper end engaged to a screw jack extending therethrough at the lower end. The exposed section of the screw jack is pivotally engaged to a platform deployed beneath a pivoted arm extending from the tube segment. The screw jack is of a length sufficent to raise the tube segment above ground for attachment to the tail stock.
