Having had many 4x4's and Hi-Lifts over the years, I can say the only way they're worth having is to have matching sockets on the rig. (And a modified jack stinger) That way, it's held from flipping. That's limiting though because you're stuck with wherever you fabricated a socket, and for me, an X-Jack or floor jack works the best. I also pack a floor jack under the cargo floor. (where the 3rd row seat was)

Another use is as a winch of sorts. But, you need the correct length of cable or strap for that to work. They'll also move rocks and logs if you get a chain attachment. So... bring one along, but just use something else to SAFELY lift your XK.
