Well it sure would not hurt to have it along,I have used one of those several times to get unstuck. Throw in a couple of long chains as well to get some reach. And leave it rigged through the pulley as well as that gives you double the pulling power,which is barely enough sometimes.Krochus is right though,if you are in it axle deep,the come along might not help all that much. I wouldn't give up though you might try it anyway,sure beats walking 30 miles.
