I've got to say, that personally, having done quite a bit of wheeling in the past 3 or 4 years with organized groups, I have never before (before Sunday) gotten stuck in a manner in which it would have been quicker and easier to have a winch rather than just getting a tug with a tow strap from another vehicle.
So, although winch's are cool an all, if you are only doing legal organized wheeling in groups, then it is rarely a necessity. Especially before you get into really extreme stuff.
I plan on buying a winch for the tracker first, long before buying one for the yj, and I'm thinking at for the size and weight of the tracker, this winch is probably overkill for me.
