I don't see 35's being easily achieved with a 2" lift on a 100 series; not comfortably anyways. 33" tires an a 2" lift will get you up the trails you're talking about. Maybe it's just me, but I'd rather suffer decreased mpg's due to full plated under-belly, sliders and bumpers then the weight of 35" tires. 33" tires, armor, and a locker or two... Good to go.
