I did a bunch of work to my hunting truck, a 92 Toyota , but the biggest thing any 4x4 can benefit from is lockers front and rear. I went with ARB air lockers and an on-board compressor. It also got a 4" lift and better springs in back, which leveled it out with a canopy since Toyota springs blow. Taller tires and aluminum wheels totaled 6" of lift. It will really crawl all locked up. It's flat scary where a locked 4x4 can go. places you realize you don't have the skillset to be. I once straddled a washout that dirtbikes had started and winter rains had carved to about 8' deep. It was on a steep-ass road on top of that, and let me tell you if it had slipped into that crevasse on one side it would have been holy hell dragging it out, with lots of body damage. Went right up without slipping a tire.
Made a believer out of me, lockers are THE SCHIT.
