Re: Hi Lift Pros/Cons and preferred placement
It all depends.
They are heavy & unwieldy, and if you don't use them correctly they can be dangerous, but they are invaluable for self recovery in sand, and fixing popoffs if you have the liftmate an offroad base accessories. An alternative is the airbag type jacks or a trolley jack mounted on a plank. They all have pros & cons.
For changing tires, unless you have hilift lift points on your sliders and bumpers, don't bother -- use something else.
I have one, I have a black belt in hilift usage, I use it regularly, I like what it can do, but I hate the size & weight of it.
