The high-tech passenger cars and trucks of today are essentially descendants of horse-drawn vehicles of centuries past. This is one reason that a good deal of automotive terminology is the same. The body is still often referred to a "coachwork," while the "dash" was where the driver of the wagon rested his feet. Even the word "car" is a shortened form of the word "carriage." Tonneau is an old French term referring to an empty space behind a carriage seat. Many of today's sport roadsters use a tonneau to cover the convertible top when it's folded down and stashed behind the seat. By using a Lund Tonneau Cover over that great big empty space behind the cab of your pickup truck, you'll turn that bed into a big trunk that will not only protect your cargo and keep it out of sight, it will make your rig look better and run better by improving its aerodynamics. A pickup bed acts like a big wind scoop, causing a lot of drag. A Lund Tonneau can improve gas mileage by up to 15%! There are many Lund Tonneau Covers to choose from: the Genesis Original, Tri-Fold, Seal and Peel, Roll-Up or Hinged Model.
