There are a few guys around here with them on Blazers and other 4x4's for grooming trails. I also know a lot of guys running them on quads, but they are limited to about 20 mph. They will climb straight up though, and the deep snow they go through is awesome. The last I heard it was about $2,500 for a set (of 4 I think, but that was on a Quad, not sure of a larger 4x4.
Here is one of an old Jeep being tested with a set, about 40 or 50 years ago. Gives me some ideas of what to do with the chain link fence!
