Amphibious vehicles aren't new, but they are still something many people don't know. That's not the case for Donn, who shows us all his craftsmanship by building one of these marvels from scratch. I can't decide which is more impressive. The fact he has all these skills and knowledge or that it only took him a little over 26 minutes to build it from scratch. I loved the video and you was having way too much fun in that vehicle and so would I! I loved the way it was built too. If I was hiring a mechanically inclined. You be definitely hired to invent stuff like a space craft of some kind. Keep up the great work. Military amphibious vehicles also have a boat-like propulsion behind which can be switched from the wheels, and like that it's using the same engine, without needing to be turned off, it's just some gears which change from wheels propulsion to boat propulsion while the engine still runs. So you won't be left in the middle of the river at the mercy of random water currents. This guy puts college trained engineers to shame. He will be king of an apocalyptic SHTF situation arises.
