I almost always agree with you 100%, however, even though I think you were trying to alleviate peoples fears of having to spend $3000 on winch/lift/tires, I still think you went a little overboard. Using the "middle" of the range you listed, all the items come to about $450.
First of all, 5280FJ, I enjoy being disagreed with. (That's what keeps things interesting around here and makes it a true "forum."
But, you're right . . . . one of my intentions was
to squelch the fear and apprehension that one doesn't
need to shell out $3k or more to build a trail rig just to attend events like the Summit.
And, perhaps with a bit of cost-cutting, someone could
get the total price down to a couple hundred dollars or so.
The organizers should have some sort of check list to make sure either the group leader, or other in each run have this sort of equipment.
Not only that, but many organized events like this (i.e., Cruise Moab) have a mandatory vehicle and equipment inventory inspection for all participants. However, yes, provided that the group leader and/or tail-gunner have the necessary gear for their group, that could suffice as well.
