Enclosed Flat-Bed Trailer When loading an enclosed trailer, fold down the rear door, which will serve as the full-width ramp, and follow the same process as for flat-bed trailers. Once the snowmobile is in place, set the brake and then secure it with tie-downs. Some trailers have a tie-down bar that is placed across the skis and screwed in by the fastening bolt into the receptacle in the trailer’s floor. Other models have D-rings in the trailer floor to which ratcheting tie-down straps are fastened to secure the snowmobile down, front and rear. When you have finished loading the enclosed trailer, fold the door up and secure.
When unloading an enclosed trailer, be certain the tow vehicle is turned at an angle away from the front door to allow room for the ramp. Fold down the front door, remove the tie-downs, release the snowmobile’s brake, and drive the machine slowly out of the trailer and down the ramp, using caution to stay clear of the tow vehicle. When finished, fold the door up and secure. Store all tie-downs in the enclosed trailer.
