Yeah, admittedly, it is an overkill build that will take the challenge out of some of my favorite trails. But on the upside, it should be extremely comfortable and virtually unbreakable. And it is something I have been wanting to do for a long time as I have been facinated with portals for almost two decades.
I do know of a few trails that may even still offer up a challenge.

'05 Tundra DC Limited 4X4, Nitto 265/70's.
'94 4Runner on Mogs, locked up, Hummer double beadlocks, 40"MTR's, Marlin Ultimate, CTIS, yada, yada...
