As a 2WD owner I am not shocked that it got through that, only thing i would be concerned with is the terrarin. Back in 1999 about a year after my parents bought the 4runner (I was 7 lol) there was a huge flood in ft.lauderdale and i was about the height of the hood, my whole family was in the truck and it did fine driving through the neighborhood without any mods like diff. breather and such. Of course this was on asphalt but it shows you that the 4runner is like a mini tank straight outta the crate. :bigok:
