You seem to be in the know so I'll ask... Those full size transits, can you fit a sheet of plywood inside? What kind of gass mileage do they get?
Not sure about the cargo dimensions, check out Ford's UK website and you should be able to find it.
They didn't release fuel economy yet, but the RWD F150 with the Ecoboost V6 gets 16/22 city/hwy. Probably the same for the Transit with Ecoboost. About the same weight and size. That would be about 25% better than the current E-Series (with A LOT more power).
Yep you can fit many sheets of ply in a Transit!! Dropped some windows in and 3 rear seats from a Tourneo, insulated, ply lining and carpeted, racked and hooks in rear..
Mine is remapped to about 180BHP and I get about 38 - 40 mpg on a run, loads more grunt = more fuel efficiency,
