Everybody wants to help you, but all you said was that it's "unreliable" and you "have a feeling" the problem is something big. You finally mentioned the transfer case lever being hard to move -- that's one specific thing.
As for the rest of it, before you go shotgunning it or getting overwhelmed by your feelings, tell us HOW it's unreliable. Does it run fine and then suddenly stall out? Is it hard to start? Does it lose power? If it runs badly, does that mean it runs smooth but weak, or does it cough and sputter? Does the weather make a difference in how it runs? Then tell us what specifically you've tried to do to fix it. Did you look at the spark plugs or check the compression? If so, what did you find? If you did start shotgunning it, at least tell us what you replaced. When it comes to electrical problems, these trucks are very simple, and a few minutes of intelligent use of a cheap multimeter will save replacing the generator, regulator, battery, and coil "just in case that was it". If a fuel problem is suspected, have you cranked the engine with the carb inlet loosened to make sure the fuel pump pumps? Looked inside the carb bowl to see if it's clean? You get the idea.
I'm not trying to be hard on you... just sketching out the basics of logical troubleshooting. Most of the guys here are way better mechanics than I am, but we need something to start from. This isn't like "Car Talk" where some girl calls up and says her 2004 Toyota makes a funny noise when she gets half way the hill to her yoga place, and the car guys immediately know that she needs to replace the rear entropy sensor which has probably been damaged by a leaking discombobulator. That show's fake, you know.
