Man, if I'm gonna try this with 2" of lift, 33x9.50 ATs and IFS, an 80 series should be a walk in the park in comparison. Get what you can done and if it's too brutal, I won't be the only one who parks at the trailhead and thumbs a ride into camp for $200 t-shirts. BTW, the main reason I'm even trying is that people get 122" wheelbase Tacomas through there (Scott Brady just recently) on ~33" tires and the only way in heck I have a chance is with guys like UB spotting.
