I neglected to mention it earlier, but many/most(?) of the Chevrolet/Marque ambulances have remounted boxes on them, circa 2003. They were originally on Ford E-450 chassis and were remounted on the new Chevy's as a cost saving measure. Here is one of them as delivered originally. It's still assigned to Rescue 29.
