Why, if the truck is equipped with a snorkel, they can operate for long periods underwater! Make the jump to watch a hoon of the highest grade tackle a river in what looks to be a surplus military truck, complete with full snorkel equipment. Bonus points for IDing the truck.

When your truck can breathe, but you can’t, you gotta be doing something right. Thanks to John for the tip!
