I don't know that I would sell them beer.... just what we need, some drunk tourist on the road, all pissed that he got his car stuck......
I personally would use straps and D rings......
Not a fan of chains, but we did pull a class A fuel truck out of the sand when it got stuck... with a chain, attached to our forklift....... the chain was rated to 25,000 was big and heavy.... but I know for a fact, that fuel truck weighed a lot more than that..... and shock is what breaks stuff, the rolling capacity isn't near as bad.....
If you are alone a lot, you might want to invest in a winch and a pull pal
