The devils advocate opinion. Woods, dust and muddy riding here. No snorkel because don’t have deep water holes, and if I accidentally flipped in a hole, hope it is not the side with the snorkel. As far as dust, just do air filter maintenance, or even buying new filters periodically is cheaper than cost and labor of snorkeling. Personally I would not buy a used snorkeled vehicle, thinking so much other stuff is likely not designed to be submerged. That said, modding your vehicle to better prepare it for its intended use is smart.
