This must be a geography thing. Come wheeling with me in Florida july through november and you will be ordering one right away. Down here our trails get flooded with water and traversing tire to headlight deep water is a regular thing here. I regularly see water above my wipers in the rainy season on trials.
I have taken the time to dissassemble the whole air intake system and seal it, as well as seal the electrical compotnents and breather extensions on my drivetrain.
Now we do accasionally have guys that come out with us that do not have prepared vehicles but they are usualy getting oulled out for new trannies, motors or some kind of electrical demon.
I am an advocet of snorkels in my area if you actaully do any wheeling. this pc is an in cab view of an xj on 35's on one of our regular trail rides.
Personally I spent 20 minutes this hole that night with water head light deep. Thanks to my snorkel and sealing work I had no problems. Except the water in the cab was up tp the ottom of the dash. On my upcoming mod list is a pr of bilge pumps 1 under each seat to keep the water levels in the cab to a minimum.
typical trails in rainy season
these are shallow areas where folks could stand on there tires and get picks however the holes encoutered get real deep and it is just part of florida "mall crawling".
