## Abstract

The present invention provides a portable gas grill for cooking food that burns LP gas stored in a 20# class vertical LP gas cylinder having a foot ring. The portable gas grill according to the invention includes a grill cart including a plurality of vertical posts supporting a fire box and a base that connects the vertical posts. The portable gas grill further includes a wheeled dolly including a generally horizontal loading platform that is adapted to receive the foot ring of a 20# class vertical LP gas cylinder. The loading platform is adapted to removably connect to the base of the grill cart. Preferably, the wheeled dolly further includes a generally vertical retractable frame member having a lower end that is fixedly connected to said loading platform. More preferably, the vertical frame member is retractable such that in a retracted position it is about the same height as a 20# class vertical LP gas cylinder having a foot ring received by the loading platform.
