Maybe I oversimplify. But I think a lot of Sprinter's better handling comes from MB's prohibition on stretching the chassis. Coupled with the relatively low GVWR, it forces builders to make a light "house" that stays within MB's chassis dimensions. Rear Overhang seems to be a big contributor to poor Ford chassis handling. I'm starting to think a lot of the cause is "house architecture." By that I mean the builder has a concept of what the rear walk-around queen bedroom should measure, then sets the wheelbase to the wheel wells don't interfere. On a 31-ft Class C, there's enough "mid-section" to get some wheelbase ahead of that bedroom. On a 27-ft, the "house" looks like it's balanced on the rear axle. That overloads the rear, underloads the front, and the coach wanders.
