I suspect that NA van people would laugh at the idea of a full size van with a mere 4 cylinders and 140bhp AND a manual transmission... that alone would mean they'd probably have to pay more than minimum wage for the drivers. 
Poor Europeans, how can they manage to move the cargo with those wimpy engines?

Almost 10 years ago I drove on occasions a brand new similar van (a Fiat IIRC) full of computer equipment and it was just fine. I think it was a diesel thought. It was as easy to drive it as a car, even better than some.
Once the Americans would have the chance to convince themselves that it can be done, and even better than the vans they are using now, it may be a success. I think the Sprinter became very popular in North America.
I think the large vans for commercial fleet is not one of Ford's priorities for the transplants these days, but I wouldn't be surprised to see the new generation of the Transit making it to our shores.
