i also got a "dog bone" from cabelas (outdoors store) basically its a metal pipe with two ends that you can use to adjust a strap to any length you need.. it has come in handy for me a few times pulling people out of the ditch across the narrow road i used to live on
one other piece of advice.. make sure there is plenty of room around you, especially if the VX is also on ice or snow, it will have a tendancy to wander back and forth a bit... and if you are on a hill.. pull them uphill! it makes it a little more difficult.. but you eliminate the risk of having them slide down into you after being pulled free
