An x in the center of the chassis will reduce flex more than boxing the rails. We usually put an x under the cab and two pieces of tubing that create a triangle out back just in front of the rear suspension. A triangle cannot change shape unless one side is shortened or all three angles change. A square or rectangle can easily change shape without shortening one side, all you have to do is change the angles in the corners. A triangle is much stronger than than a square. An x is basically two triangles. But everyone is entitled to there opinions. This is my thought on the subject. Let me know how you guys feel. Happy cruising. Or building. Whatever stage your at, enjoy it.
