The only thing that defeats it is climbing out of a stream - at which point it submerges the rear engine and drowns!

Doesn't that just mean you should always back it out?

You couldn't drive a Model T up a hill, because there was no fuel pump and if the carburetor was higher than the gas tank the engine quit. But you could back one up over almost anything.

In the mid 60s, Ford made something I think they called the "Scout" that the Army used for Administrative Vehicles. It couldn't get more than about 100 feet up anything over about a 20% grade, because the float bowl was on the front of the carb, and if the nose went up it spilled fuel into the bore and flooded the engine; but you could back it up a 48% grade with no problems, as I did for more than 50 miles one week at Flagstaff AZ while running "high altitude" tests on the XM410E1 ca '65.
