Ya know, a Hi-lift by itself can be incredibly dangerous. But....when I actually found out about the attachments made for Hi-lifts, on account of my rock crawling, they take most of the danger away, and I find myself using the jacks more often than not. Of course, with oily hands the occasional runaway can still happen when going down, so be prepared to just walk away and let that guy ratchet until its done. The strength and versatility of a Hi-lift can be utilized and the danger tamed with the right attachments. Of course, none of this matters if you don t have enough bumper to use a Hi-lift. I even have a bead breaker somewhere for one.
