1984-1989 Toyota 4runner.
Toyota reliability and build quality, 4WD and very capable, parts available the world over when needed, smaller overall size in width length and height for better trail access, removable hardtop and soft top options, affordable to purchase and build, large aftermarket for support/upgrades, many affordable engine swap alternatives available if the original Toyota 22RE I4 or 3.0 V6 is not enough power for you, solid front axle stock in 84-85 models IRS front in 86-89 models, long enough in length to sleep within along with room for your junque, vintage kool, currently appreciating in value, easy to repair on the trail IF you have the parts with you, lighter in weight for better fuel economy and less trail impact, you can register these with "antique" plates due to age, you can purchase "Agreed Value" insurance for these trucks and on and on!
WOW!
There's a lot to like about the first generation 84-89 4runners.
I guess that's why I have 2 of em!
