I have used nerf boards in good condition. Has been used just 20 000 miles, then Ford was upgraded to Rock Slidind Boards(200 pounds). Nerf board weight about just 45 pounds, about 6 fit long. Fits all Ford E series vans. Price is just $250 compare to new $750 with istallation. Local pick up (Fresno). Delivery within California with installation available. No shipping.
