It is a rebuilt Unimog- they look funny, but all the weight is within a foot of the tops of the wheels. On this thing, might even be lower. As a result, you really, really have to work at flipping one unless you do something silly like take a turn over 40 miles an hour. :P They aren't really for the interstate/autobahn, but there used to a lot of footage of them doing things like climbing 40 degree inclines on the web.
