Thanks for the post!
Seeing your vehicles reminded me when I first saw these with the high-mount air intake at our caravan park in Perth my initial reaction was 'serious campers, must have to ford the odd creek'. But when we took our day tour from Alice to Uluru and saw all the flash flood warning signs I thought 'not necessarily fording for campers, but surviving for anyone caught by flooding'!
Safe travels!
Yes the snorkel helps in keeping water out of the engine when crossing creeks and rivers. It also helps keep dust intake to a minimum. Being higher up, less dust is taken in and also cooler air.
Thanks for the feedback, good to know. Away for a bit and catching up!
