A trailer frame includes an axle-carrying portion and a tongue. The tongue includes first and second curved drawbars, each defining a convex surface. The convex surface of the first drawbar faces the convex surface of the second drawbar. The facing convex surfaces allow for an increased turning radius of a tow vehicle connected thereto by increasing the distance between the rear corners of the tow vehicle and the tongue.
