I purchased the Power Caster years ago to move my trailers around my yard. The Power Caster does a great job. It also has a switch and wire harness that you wire into your electric brake circuit that allows you to lock the brakes to hold trailer on a incline so it does not roll away when using. I went with the A/C powered unit rather than the 12 volt battery unit. The only issue I have had was the face plate on the switch box is larger than the box, and the sharp razor like edge has sliced me open a few time while turning the trailer. I contacted Power Caster about this issue, but they just blew me off.
