Saw a 2008 go thru mud/water ... how deep can it go?

I saw a video of a Tacoma gowing thru water up to the grill. Just how deep can the Tacoma drive thru?

How deep can it go with a snorkel?

I saw a thread on doing the read diff breather to allow it to drive in deeper water, so i would take that mod being done into account. What other things need to be done for deep water travels? I heard somethign about relocating a lead for the starter, but i dont even know where or what i heard.

I also heard the door seal are average on a Tacoma. Any way to make them better?

What about wat up to the window level...wouldnt the water get inside the door and thus get the electronics for the power windows/door locks wet? Are they sealed? Should they be sealed?

I would love to do this once or twice in my life. Maybe not with my Tacoma, but what abotu something about half that deep?
