Abstract: This invention relates generally to a portable shelter for an automobile which is lightweight and easily assembled. The invention utilizes base plates which are adjustably placed under the wheels of the sheltered vehicle for securely anchoring the shelter structure. Independently adjustable vertical support bars are attached to the base plates and support a canopy. Additionally, cross-braces which are adjustable in height and adjustable in length are positioned at tire height to that the vertical support bars of the structure can be securely braced against the vehicle tires. This provides superior lateral support against meteorological conditions without the need for external stakes or guide wires, and without contacting or damaging the body of the vehicle.
