We've got a 4Runner at work. 2015 or 2016, I think?
I've never been crazy about it. Weird seating position and the suspension feels like it has no travel - not exactly harsh, it just feels wooden and dead. But it's also running on truck tires (Duratracs, maybe even oversized a bit) so that wouldn't do the ride any favours.
No idea what's under the hood, but it doesn't feel very powerful. Steering is vague, too, so overall I find it a pretty crappy highway cruiser.
But it's probably been a smart choice for the company. Think it's got around 250,000 km, much of it pounding down crappy bush roads, and I don't believe they've had any issues with it.
RE: the suspension, the difference between the TRD Pro's suspension and the few other 4Runner models I've driven is remarkable. All the TRD Pro trucks have incredible ride quality, made even more remarkable by how well they work when really punished off-road, too.
Last autumn at the annual Automobile Journalists Assoc. "test fest" event, Toyota had (probably the same) TRD Pro 4R available. There's an ATV / snowmobile trail that's made available to us for the trucks and off road vehicles that's frankly, not all that challenging, but there are some big splashes and if you start taking the 'whoops' at greater speed, the diifferences between a mediocre suspension set up (or, in fairness, one meant for towing), versus and off-road set up like the TRD Pro, are considerable. The 4R can be hustled along at speeds that would bounce most of the other machines into the woods.
As others have said, having the V8 underhood is the answer. I'm currently actively looking for an early '00s 4R with the V8 that doesn't have a rotted out frame and isn't wildly overpriced (yeah, good luck, eh?). I love the idea of having an absolute sh !t-kicker truck that I can tow with and/or chase the g/f off-road in her Wrangler, and trust that it should last forever as long as it doesn't rot.
