I love me some full-size Broncos.
If the government ever came down and limited us to each only owning one vehicle, that's what I'd have.
2nd-gens are my preference as they're nigh indestructable. Weakest point is the engine where your choices are either of the 335-series motors: the 351M or the 400 (I'm not saying they're weak - just compared to the rest of the drivetrain). I'd spring for the 400, that particular 351 was made due to the popularity of the displacement, and is just a destroked 400. Many people consider them boat anchors, though my father has one with cleveland heads, headers, and a 4-barrel that says otherwise. The rest of the drivetrain is either a C6 if you go auto or NP435 if you go stick, into an NP205 gear-driven transfercase, out to a Dana 44 in the front and Ford 9" in the rear.
3rd gens ditch the 385-series V8s in favor of Windsor blocks - 302s and 351Ws. The 300 I6 is also offered. Transfercase is the NP208 which is weaker (chain driven), but has better gearing than the NP205. Around 1984 the 9" rear is replaced by the 8.8", though the 9" was apparently still an option as I had an '85 with one.
If you go 3rd gen, I highly suggest going for a fuel-injected truck, avoiding the push-button transfercase that Ford went to for a while (my '96 has a properly shifted t-case), and ditch the auto-locking hubs for set of manuals (the autolockers break when looked at funny). Skip the 5.0 and head straight for the 5.8 if you go V8, the 5.0 is just as thirsty and has noticably less torque.
I suggest Broncos for a few reasons:
1) based on F-150 chassis. Parts are EVERYWHERE.
2) Short wheelbase, excellent turning radius - doesn't park like a truck/SUV.
3) 2-door with folding back seat, lots of space when you need it, 5 seats when you need to people-carry,
4) Removable top BEHIND the driver's section - this means even if you pull the top off a few times, it will NEVER leak above the windshield the way a Blazer or Ramcharger will.
5) Handles surprisingly well. I'd autocross mine if everything else was broken down, and I have rallycrossed my old '85 with no ill effects.
