Nice looking rig for a starting platform.

You shouldn't have any problem turning it into a capable hunting/trail rig even with the IFS. The IFS is a lot stronger and more capable than the rumors and forums might lead one to believe. The Toyota first gen IFS is actually pretty durable, as long as you understand what it can hit at speed and what it can't, i.e., you can "Ivan Stewart" down fire roads with ease, but you don't want to hit basketball size bolders or bigger at speed, doing so tends to bend/break steering components. There are still some of us holdouts who still wheel rock trails like Rubicon and Fordyce with IFS set-ups, granted we can't run every obstacle, but we get through teh trail without much issue. The IFS also offers a better street ride and handling, something important if you are going to put a lot of seat time in driving to work or long trips to your favorite hunting sites.

I would set up the rear with an ARB or Toyote E-locker, forgo the front locker and install dual cases. I run a front auto locker in my '91, but it isn't a daily driver, so I don't have to be concerned with the driving quirks auto lockers have on snow and ice. You could always install a front ARB later if you feel the need, or swap to an SA if the IFS nolonger fits your needs.
