The wipers whilst underwater is what gave that truck the ability to become a submarine.Truck made in Japan, firefighters made in Australia, enough said!This is the best commercial Isuzu never paid for.I got one of these, I used it hauling live fish and crab. I just donated it to my fire department, I had been telling the Chief how useful it would be in a flood, but I had seriously underestimated the depth of water it could ford.Actually, this is how the truck collects water to put out fires.
