If you're short on storage space, but like to go exploring or sometimes have to deal with wild weather, GripTrack could save your life. Made of durable plastic, these foldable traction tracks can get your pickup truck or sport/utility vehicle out of a sloppy, sticky, or sandy mess by giving the tires better traction. Just toss them in front or behind the tires that are slipping and modulate the throttle. A pair of GripTracks and a cloth case costs about $40.
