I have one on my roof rack, attached with bolts, washers and nyloc nuts. Mostly to make me think about whether or not it's really the best tool for the job while I undo it, but also as a theft deterrent:
It sees occasional use in pulling posts and the like, so I don't regret owning one, but if it were to walk off, I'm not sure I'd rush to replace it.
If you look carefully, the bolts are plenty long, and without an impact gun it takes a while to spin the nylocs off. Plenty of other external stuff on the van that could be removed with similar effort.
