The trick with water is, Slow as possible and as fast as necessary... If your making a wave that goes over your jeep your going to fast. You want to push the wave, not drive through it.
Whether you have a snorkel or not, a gulp of water isnt good. Little splashes and stuff wont do anything but actual gulps are a bad deal. Just ask how I know...lol
