Hi, I am looking into buying a 2014 Silverado 2500HD with 6,6L diesel engine. My issue is that has been an ambulance, sold without the bed. I tried to figure out which bed length to purchase, only to discover something strange with the wheel base. It is registered as 3785 mm, meaning 149 inches. I would have thought the wheel base to be either 153 or 157 inches? It has the regular cab. Anyone know if this is a normal lenght? Or something specific for an ambulance? Regards, Johan Soderberg
