Think of it as insurance. You carry it so you won't have to use it. Not having it increases the cosmic chances you'll need it.Great point about the HI-Lift jack. I used to cary one, but over the years found it to be heavy and I can only remeber one time when it was the only tool that would do the job. I have one for home use, but I don't carry them anymore. But, I'd like to learn about alternative uses, maybe Ill add it back in.
