Long drive shaft assemblies can absorb a good bit of power and are known to be difficult to tune out vibration and 'thrum' @ higher speeds.
What? Do gassers have this problem? Do medium duty trucks have this problem? They actually have some advantages over pushers, such a better cooling, easer access, 50+ more hp to be useable, no hot drivetrain under the bedroom. Yea, I know, no air suspension or brakes, more noise, well maybe. The front diesel has a redline of 3,200 RPM, compared to 5,400 RPM for the ford gas. If the suspension is properly tuned, with enough travel, it will ride pretty good. FORD has engineered their suspension per the manufactures requests for a soft ride, and they got what they asked for, when the MHs are empty. What they need is stronger springs with more travel before hitting the bump stops.
