Abstract: A snowmobile trailer has a ramp which is connectable to the platform and frame assembly in two positions at the rearward end of the trailer for loading two snowmobiles in adjacent storage lanes and is connectable at an angle at two positions adjacent the forward end of the platform and frame assembly for unloading trailers under their own power forwardly of the trailer to both sides of the trailer tongue. A V-shaped deflector above and forwardly of the trailer bed deflects the snowmobile skis as the snowmobile moves forward to steer and guide the snowmobile onto the angularly related ramp for forward unloading. Upturned marginal flanges on the ramp also guide the skis to steer the snowmobile during unloading and loading.
