Our French brethren, veritable the masters of gastronomy, thought all that up to its zenith years ago with the Citroen (SEE -TRo Enn!) HY van.! A totally flat floor unit with no wheel wells being FWD. Coming in various lengths including very long wheel bases, it even had a kneeling ramp feature at the back for ease of access into the rear.
Its also has that nice retro look which is a customer attraction anyway, and a nice departure from the older GMC's (now Workhorse) American medium duty van preferred as roach coaches here in the US & often used by our Latino community!
Vive la difference
