Our transportation: a Mercedes (with 4 1/2 foot tall tires) and a beefed up Toyota Landcruiser. Let me direct your attention to the snorkel on the drivers side of the Mercedes. It supplies air to the engine so it continues running when it's submerged in water. And, yes, we drove through streams. In addition, we had to stop to let air out of the tires or, put more air in, depending on the terrain.
