That submerged diff is fubar, however.

Absolutely. The build quality is always top notch on these.
I wonder how many years that picture has been circulating around on the 'net.
I think, years ago, I read an article about a car club in Houston using donks to help get to people trapped in flooded areas.
Submerged diff doesn't matter if you don't go fast enough to make any heat, and you keep moving to stuff doesn't oxidize in place. Should be good for tens of miles at least.

From my understanding the main ways water gets into diffs are 1) Slowly leaking in through the seals in prolonged submersion, especially if not moving 2) Getting into a wide-open breather port that was never designed to be submerged, and 3) A warm diff with a valved breather port hits the water, cools down causing a vacuum to form in the diff, breather port slams shut, but there's still a vacuum so it sucks in water through the seals. A diff breather hose would solve 2 or 3.

Oh it can definitely be a real problem, but even full of water, the vehicle pictured above would probably be just fine for some time. Not long term, and the rust may render things beyond repair. But in a pinch, say driving around a flooded neighborhood hauling folks to safety, not an issue.

That's my take, as well. And that's the first redeeming feature I've EVER seen for that particular "custom" fad
