Has anyone here used a come-along (AKA Griphoist), which is a type of "manual winch"? I have a friend who offroads with one and swears by it as a cheap alternative to a winch when you can't afford one- he says it has saved his a** more than a few times out on the trail with his F150 FX4 Offroad. Apparently, some are rated up to 8,000lbs! Any recommendations on brands?
