If any of our Motown readers would like to look at this truck a little closer, there is one parked behind the Chrysler Mopar parts facility in Centerline, MI. Pull in the visitor's parking lot at the most southern of the buildings there, and you'll see it parked behind the gate behind the building due north.
FWIW, it didn't look any bigger. I think it's a just re-skin, but I could be wrong.
