Abstract: A canopy style trailer cover for protecting recreational vehicles mounted on a trailer includes a plurality of U-shaped frame members, each having a pair of opposing arms that terminate at a distal end. The respective ends are pivotally joined to the side of a trailer. A cover member having a substantially semi-circular cross-sectional configuration is mounted over the frame members. The pivotable frame members allow the cover to be pivoted and collapsed toward the rear of the trailer in an according style fashion providing convenient access to the vehicle.
