Analysis

The private pilot reported that he was landing the tail wheel-equipped airplane at a privately-owned grass airstrip with a "slight" crosswind. He reported that after touchdown, during the landing roll, he lost directional control of the airplane and it collided with an unoccupied parked vehicle adjacent to the runway. The collision resulted in substantial damage to the right wing. No mechanical deficiencies or anomalies with the airplane were reported.
