I agree that the E450 is the best of the bunch. The only thing I would do concerning the extra rough ride in back on the lighter weighted rigs would be to "tune" the rear suspension to better match the actual load it carries. Too much extra capability will make a rough ride even more rough. Many RV owners complain about their rig thrashing around. Maybe something can be done to soften the ride.
How to "tune" the rear suspension is another topic involving the removal of the proper amount of E450 leaf springs. I have no personal experience to provide, only theories. I imagine it would begin by comparing the leaf spring packs of the E450 to the E350, learning what you can from the differences. Also compare your E450 actual rear axle weight to the limit of the E350 of the same model year. If you are rear axle weighs 1000 less than what an E350 rear axle can handle, then you want your leaf stacks to be that of an E350. Again, my theory alone.
