Some research to add for you. May not be Tahoe specific although 2nd link sort of does.
^^Guys have good points to consider.
Almost every other 4x4 in Australia runs a snorkel for the dust and the rivers. They actually have packages from the dealers and plenty of 4x4 shops to outfit them.
Toyota Landcruiser, Nissan Patrol and Mitubishi Pajero are king there. Plus the Hi Lux, Ranger, Triton on the mid size.
