Hey! My RV doesn' sway at all. Hmmm. What a joke. All large sided vehicles sway with cross winds. However, not all of that sway is felt in the driving vehicle. In fact 5ers sway a lot. So much so all chairs etc. are tied down but you feel amost nothing in the PU. Well loaded TTs with a good hitch set up still sway but not much is felt in the PU. When RVers move to a MH and experience sway they are surprised. You feel all of it in a MH. Years ago I drove my 5ver down the highway at 70 to 80 mph and never felt a thing in my PU. Then I followed other 5ers. Whoa Nelly Belle. Does my 5ver sway that much? Yup. Doubters just watch the big rigs for a while. You will see a huge correction. A few moments later you will feel the same cross wind they felt. All large vehicles sway. JMHO
