Hmmm....I have to look at that again. The Fiat Ducato/Dodge Promaster is more spacious in the drivers cab than the Chevy or the Sprinter. Looks about the same to me on the Transit. If you are too big for the Promaster, then you probably need a class A.
It is tight in that cab because the cabinet is shoved tight to the driver's seat. I had that situation in my 2005 Pleasure-way Plateau and hated it. Also, that guy was a tall guy. He had to be over 6 ft. tall. They should always use Tom Cruise size guys as presenters in Class Bs.
