My Ford has those same power retractable ones like the Ram in Sactoller's picture. They work fine in warm weather when they are clean, but run them on wet gravel roads and the little stones get in the front hinge and they don't work so well. They let you know pretty quickly that your battery is low as well because they either don't go down or they won't retract fully or at all. Fine for a soccer mom grocery getter, but not for a work truck. KIS and get those heavy bars in Rock Chucks post.
