after the truck runs and drives, and is safe (brakes, lights), buy some new mud tires (31s) put in a rear lunchbox locker (spartan)
DON'T overbuild your truck. DON'T take the whole truck apart. don't lift it.
buy some good tow straps, and a proper long handle shovel, not an army folding shovel.
with some good tires, and a rear locker, the truck will be easy to drive, go lots of places off road, and still be useful for lots of things.
all of this is assuming you have a nice to begin with and want to keep it street legal.
if this is some backwoods farm beater, then hog out the fenders, install some cheap 35s and weld the rear diff, while you go looking for some 3/4 ton axles so you can run 38s, until you break the front end enough, then you can get a 60 and run 44s until you break the truck enough and cut off enough body panels that you might as well do a 4 link and coilovers and take the truck to full buggy status.
then you'll have a ripsnorting buggy, locked, on tons, with 44s and tons of armour, and you'll be wishing a simple truck you can take to home depot and go fishing and camping with and you'll get a clean blazer, and put it on 31s with a drop in locker, and the whole process starts again....
