Move a Trailer with a Dolly - If you have a bad back, forget the lift-and-lug method. Instead, drill a hole in a dolly and add a bolt and a stack of washers to create a knob. Slip that knob under the hitch socket, lift, and push or pull.
Heavy-duty dolly with integrated drive takes the hassle out of moving your trailer. Simply connect your trailer, turn the crank, and guide the trailer with the steering handle. The drill attachment lets you use your cordless drill instead of cranking.
