4. DUKW “Duck” Amphibious Truck
The main amphibious vehicle of Allied Armies in the Second World War was the “Duck.” This was basically a truck with an open bed, waterproof floor and a propeller on the back. And it had the ability to carry personnel and cargo over large bodies of water.

Produced from 1942 to 1945 for use in Normandy, surprising numbers of those vehicles are still around. They are not budget-friendly, but you can use them for just about anything, from tourist tours to ferrying people across rivers.
