I am currently in the market for one as well as a winch. picture this, a tale from a buddy of mine.. sliding down a hill forward and got wedged up against a tree with no traction.. he had to run his winch underneath his carriage to a tree behind him and damaged his fairlead and some other components. yes, he could have had a movable winch but that adds a significant cost. otherwise a hi lift jack would have worked to pull him backwards up the hill... another scenario, you're in some really rough terrain or extreme rock conditions and you need to replace a tire, would a bottle jack work as well as a hi lift? I truly have no experience with either I'm just looking at this from a common sense standpoint and what I've read on the forums. I would never try to use a hi lift jack on the highway to replace a tire that's what the scissor jack is for, however it seems to me with a couple links of chain, strap, and a hi lift jack you can pretty much get yourself out of any situation out on the trail. please, point out the flaws of my logic I want to have the best setup for getting myself out of trouble. I'm a new Jeep owner and don't have a lot of experience in really heavy situations.
