Portable track vehicle for backing trailers uo

depending on how heavy your trailer I have used a two wheel hand held dolly to move my 28 foot 4000 lb trailer short distance on flat hard ground. it had a long white T handle and to stop trailer from moving all I had to do was turn the dolly at a 90 degree angle to the direction of movement. Worked great and was cheap but heavy duty and not the one from HF.
