I'll admit I haven't watched the vid.
The description however, sparked a memory of seeing a TV program where the proper use of a land anchor was shown. I think it was the Bushman bloke (many apologies, I can't recall his name). Anyway, he ran the cable over one of his spare tyres, to the anchor to achieve better leverage. Seems to me that you usually have a spare tyre, so why carry an extra bit of kit?
