I think the Sprinter, Promaster, and up coming Transit will address that even better as regards handling and ride.
Many have had this discussion before, but I still can't wrap my brain around the physics of how any PASSIVE suspension system - except passive full air - is going to make a 10,500 lb. coach on a 14,500 GVWR chassis, both handle nice and ride nice at the same time.
Expensive ACTIVE suspension systems can do this. I know a lot of folks bad-mouth good old leaf springs - but lbs. is lbs. and weight has to be dealt with in accordance with the laws of physics unless computers are used to intervene in real time to tweak things. For me, I'm willing to give up a nice ride for the other advantages you get when carrying a load around full time that is way under the chassis design-maximum.
Pretty well summed it up, Air suspensions are common outside the U.S., maybe become a lot more common in the US. Winnebago has a Class A on the Sprinter, the Ducato stretches out to 28ft and very good handling and ride.Other options that could be used are not available in the US, where you see to have basically variants of the Ford Van
