Steco is now building an aluminum version of the frameless Hauf dump trailer, available in 24- to 40-foot lengths. Customization options include varying widths and lengths; external or internal dump-cylinder mount; various tailgate options, and a variety of suspensions, wheel, and tire choices. Today's version of the venerable bathtub-style trailer design uses the same continuous weld of the U-formed side posts, the same smooth bed with easy-to-clean corners, and the same top-hinged tailgate with remote air-controlled open and lock as the original Hauf. It has been modernized and improved with up-to-date running gear.
