No one else has reported the issue to us, but you won't do any damage by driving in 4WD high on the highway.
You're getting into the Colorado at about the right time, when they've done around 100,000 km. If you're going manual check the clutch, that's a bit of a weak point, but other than that go for the best car you can find. One thing to focus on is wear and tear from use as a work vehicle. Look at damage in the bed, dents and scrapes on the body from being worked hard on the job site. Overall they're a pretty good thing.
It appears that most, if not all, one-tonne utes are affected by the same clutch problem. It's the same story on pretty much every ute, no mater the brand, and the common complaint is premature wear and/or slipping and shuddering. I agree with you that 60,000 km is too low for a clutch to be worn out, but you'll find your warranty clearly states that the clutch is not covered. You could argue your case for Holden to cover the cost of the replacement, or you could have a better aftermarket clutch fitted.
It would appear that the vibration is coming from the driveline, and the clutch being part of the driveline could well be source of the problem. It's worth getting it checked.
On the surface it would seem that there is a problem with the clutch, it could be that the pressure plate has collapsed or something similar. Pulling the gearbox out should enable the mechanics to find the cause of the problem.
