Need clues to identify a Sprinter I recently saw

I was on Center Street of Fernandina Beach Sunday, and saw a 19' B late model Sprinter Van. The van was painted charcoal gray with blacked out windows and matching alloy wheels. An interesting feature was that the AC unit was mounted forward of center, like the old Dodge Explorers, rather than toward the rear like a RT, PW or LT. It had an matching awning, also.

This was a sleek-looking Unit. Does anyone know who might have built it? I do not think it was a Sport Mobile.
