This invention is directed to a kit of coolers that offers a number of improvements over the prior art. The coolers are modified to specifically accommodate frozen gel ice packs instead of ice cubes. Because there is no spill water, the coolers open with front-facing pull-out drawers. The coolers stack atop one another with interlocking parts. Easy transport is provided by a handle and wheels, which may be attached to the bottom (main) bin or alternatively on a separate dolly. Internally, the cooler bins are compartmentalized horizontally or vertically with dividers. Hollow spaces within the walls and dividers of the bins accommodate frozen gel ice packs. Overall, the coolers are easier to pack and unpack, stack, load into a car, and transport on the ground than conventional ice chest coolers.

A luggage cart assembly including multiple luggage containers which are vertically arranged, and one or more of the containers are pivotable such that the container can be accessed without having to move the other containers, where the container includes first and second attachment members to attach the container to the luggage cart. When the first attachment member is detached from the luggage cart and the second attachment member remains attached to the luggage cart, the container is pivotable relative to luggage cart and the container is supported by the second attachment member. The first and second containers may be vertically separated from one another in some embodiments.
