I've had my 48" Hi-Lift since 1999. Have used it in my TJ countless times off road and on road. Even had to use it once in conjunction with my winch to get over some big rocks on a hillside. This is a tool that belongs with the avid off-roader. But if used incorrectly it will get you. Read the directions and know how to use it before you go off roading. Learn to use it in your driveway is not a bad idea. Word of caution, before flipping the switch to change directions, insure the handle is locked in the upright position. If not said handle will come flying up and severly mangle anything that is between the handle and the jack (like you).

Keep it inside, the mechanism does not like dirt + thieves have to work harder to steal it. But insure it is mounted solidly. It weighs a lot and will kill you in a roll over. Bungee cords will not secure a jack.
