Acknowledged. So I guess my question is "why do I need a snorkel?" My assumption was water protection during water crossings. I believed the secondary benefit was clean air intake during mult-vehicle convoys. If the answer is only clean air then the supplemental air filter makes since. I could then use an air source to clean air filter 1 while using the replacement air filter. I have no plans to go amphibious. So the axiom of "turn around don't drown" is in order if the snorkel is not designed for deep water transversing. Thoughts?

From what I have read, Safari and maybe 1 or 2 others are made for water. Others like Toyota OEM snorkels are not (only dust). They are not completely sealed, and have to be modified by using silicone on their joints to waterproof them. Either it was Ronnie Dahl, or Andrew St Pierre White, or Micheal ? from 'seek adventure' who did a video on that very aspect.
Out here, it is desert dust, not water that could be a problem. If you are convoying in large groups, the idea of being
strung out for miles because of dust concerns will be problematic and I imagine irritating if your at the back. aka... Last out on the trail, last into camp (tail gunner group). While it has not been a problem for me in vehicles, it has been for ATV groups I have gone with.....(choke/sneeze) ugh.
I know Andrew St Pierre did a morning maintenance cycle of cleaning his air filter by your expressed outside source (air compressor) method. It was amazing how much dust could accumulate in a days travel.
The tail pipe concern,....YES, so lesson learned, do not shut your engine OFF, until your either out of the water, or you have a modified high exhaust extension.
