The Ducato/ProMaster is very wide for a van. Inside width up to 74 inches is about 4 inches more than Sprinter. Side walls are also more vertical than most vans. It's also wider than Ford and Chevy vans.
Most camper vans in Europe are based on Ducato -- 2 out of every 3.
Class Bs are not supposed to be as wide as full size RVs. They're supposed to be smaller. And narrower too. It's a niche market, not meant for everyone.
