What is the big deal about frame flex? Frames need to flex somewhat, or the rest of the coach takes the brunt. The coach just needs to be designed correctly to account for the flex.
Well, my old '08 Ford had frame flex that would resonate around 45mph. When in resonates you get 'g' amplication that potentially could lead up greater problems. Not saying this happens here, but it could. Boxed frames like in the Chevy and RAM solve that problem. Also the frames used in the Mobile Suites and Lifestyle, and a couple others won't have that problem.
They all resonate. A boxed frame does not magically make this issue disappear. It might change the frequency but not eliminate it. All automobile manufactures have departments where there role is to minimize this phenomenon. It may be by attaching something to aid in cancelling out the response or designing it to a frequency that will hopefully be experienced less frequently.
