I think he is looking for more substance beyond referencing unspecified ROW aficionados and their preference for the HZJ78. I know i would be interested in knowing what criteria separate a soccer-mom station wagon from a real off-road truck.
Thats is not a question, thats an initiation for an e-argument; you know the difference you just want to debate it. If I spent $70K on an SUV and some said “oh is nice, but for 4 wheeling is kinda meh” I'm not sure I'd want to read it either. What I have posted is my opinion of the UZJ200, but in no way do expect others to agree. This is the interwebz, its all opinion...
Now for more opinion….
The 200 is not a bad truck, it sure does have some nice features. (Much nicer than many USA SUV platforms.) With 300+ HP you can sure tow a lot. And those cool seats are….wicked cool. But, by design (its target market), its a luxury SUV targeted to the wealthily, not an off road platform. Sure one can put a bull-bar bumper and winch on one, and set of Duratracs, and try to make it look like an off road truck. However it will take a lot more than that to get it to perform well on unimproved roads and trails.
FWIW, I know of a few people who bought 200s and after two years traded them in for HDJ78s (and another who is about to trade in for a Y61 Patrol). The UZJ200 chassis' are just not durable enough for constant duty on Costa Rica's unmaintained roads; bushings, bearings, brake pads are wearing out exceptionally fast. To me that says a lot, but thats just me — and my opinion.
The UZJ100 was Toyotas contestant to gain US luxury SUV market share, and that it did; at least 1990s models came with lockers. I think the UZJ100 is a great value right now and highly reliable; front diff is its Achilles' Heel.
I look at it this way: UZJ200 is to the HDJ78 what the Land Rover LR4 is to Defender 110. The former being nice luxurious rides and the later being designed for off-road use--from marques who exemplify durable vehicle design.
The OPs goals for one truck is tough. His JK Rubicon is a great off road platform. The towing/off-road equilibrium point is tough one to achieve.
