I actually drove an extended Ford E-350 Panel with eight doors for a couple years in the 80's. It was divided into three sections in the back plus the drivers compartment.........The compartments in the back were for the inmates.......lol
When it came to Auction I tried to buy it, but it was taken off the block and sent to Germany for the Military....Hopefully one of the German Vanner's bought it when they sold it.....
It was a company near Louisville KY that took new vans and modified them right off the line for police and corrections use. Same company widened the Dodges and Chev's by a foot for Ambulance use. They however are long gone........
