Abstract A trailer for use primarily for transporting vehicles such as snowmobiles, in which a bed is mounted on an undercarriage with the wheels of the undercarriage near the longitudinal center and in which an opening is provided at the front and rear ends of the bed for unloading and loading a snowmobile. A draw bar is pivotedly connected to the underside of the bed and is adapted to swing laterally with respect to the bed to permit the bed to tilt both forwardly and rearwardly for unloading and loading a vehicle. The wheels may be positioned laterally beyond the basic part of the bed, and a fender - compartment combination having a longitudinal cover thereon is mounted over each of the two wheels.
