Interesting video, with the hanger system that was on that RV he definitely needed the cross bracing being the spring eye being so far away from the attachment point of the hangers, a whole lot of leverage can happen on the hangers with that system or any system like it that moves the spring eye away from the top of the hanger in my opinion. Most hangers are welded to the bottom beam flange which also lets the hanger flex. Lippert uses a little piece of metal welded on an angle to help with beam flexing but the proper way to do it is with a full gusset welded in from flange to flange on both sides of the I-beam, like I pictured on the left side of the beam pic, where the hangers are attached. Boxing in the outer end of the hangers would also help. Tried to enclose a drawing, hopefully understandable.
