If I were to build a new-to-me non-rock crawler rig, it would be one of these. I'm starting to see these rigs pop up, with many built. It is pretty cool that you can call up ARB and get them to send you Toyota Prado equipment (same body and underpinnings as the GX470) to pimp these trucks out.
I mean, crap tons of power stock, solid drive train, 5 speed auto trans, traction control (not lockers, but better than open diff), low range, roughly the same exterior dimensions of the FJ80, better MPG than any rover I've ever seen, probably fairly reliable, and then you've got all the comforts of the Lexus (preferred by the womenfolk over...say...the interior of an ex-army rover). It gets hard to beat both on and off road.
