I recommend you get a 4runner. Yes I'm bias (own both 3rd and 4th gen) but having worked on both for years I still say 4runner.
The 3rd gen is a great option for the size and what you get stock. This is our current offroad vehicle.
With this option:
-97-99 models you can find both auto and manual 3.4L (damn reliable) motor with a factory rear e-locker
- 00-02 models didn't have a rear locker option but had a 'center diff lock'. Basically it allowed you to have a setting like all-wheel-drive. It's ok but I'd look for a 98-99. Which brings me to my next point.
- 97-99(00) the transfer case is shifted manually. This is more desirable that the 00-02 push button/manual that gave you 2wd-awd-4hi-4lo that uses motors. Most people rarely or never use 4wd so the motors may get sticky. Find a manual shift t-case.
- reliable motor, good manual transmission, good auto transmission but I would add an external cooler if it doesn't already from factory.
- Rear axle is toyota 8", strong with no needed mods. Lots of them had a factory rear e-locker. If it doesn't you can swap a axle in later or go ARB, Yukon, etc. Front diff is good, aftermarket lockers available. be aware of cv angles when doing a lift, no more that 2.5-3" up front.
Gearing is mostly 4.10s but You can hunt around and may find one with 4.30s
- Mod friendly yes. You will have a few more options on the 4th gen but the 3rd gen still allows for many aftermarket options on lifts (fox, king, Icon, ome, toytec...long travel, mid travel, how big is you budget? Etc), full belly skids, bumpers, lockers, optional factory supercharger + add-ons, armor, you get the idea.
Armor parts are available but take a few weeks to build, it's not a jeep so be prepared to wait for some things to be built to order.
Overall good vehicle daily and weekend wheeler. The 3.4 is easy to work on and maintain.
The 4th gen 4runner (my wife's V8) is also a great option. You have the option of a 4.0 V6 or the 4.7l V8.
- 4.0 is a good V6, good power and there is lots of motors out there. Find one with GOOD maintenance record and should give you plenty of life. Factory TRD supercharger is available.
4.7L V8 is a beast, love this motor. very simple and easy to work on. Maintenance is low and wallet friendly.
- it is a bigger vehicle with more interior options.
- suspension very similar to 3rd gen, reliable, and lots of aftermarket options from mild to long travel setups.
- For this model I recommend looking for the V8 but will have to settle for AWD-4lo with center diff lock.
V6 models do have a 2wd-4hi-4lo via dial selector on the dash.
- they all have a electronic shifted transfer case. If you are looking into buying one shift it a few times between settings to make sure is not sticky or stuck. Like I said the average owner (in CA) will never or once a year snow trip shift into 4wd.
- a few more overall options on the aftermarket world than the 3rd gen.
In conclusion either with toyota or Nissan, each model has their quirks and common failure points I suggest checking the forums for both and see what you may encounter.
Either vehicle you decide with have it checked properly by a shop before purchase, this can save you a big headache later on.
