In stock form and with 4wd, yes, you can do what we've labeled as green trails. If you have skid plates, a lift, and even lockers that'll step the game up a bit. We do have several crew cab Frontys that run with us and they've got no problem if they're properly equipped.
If you can make it out, I'd encourage it. Outside of the trails themselves, you'll get a chance to hang out with a bunch of Nissan folks, check out our set ups, meet vendors, and get ideas that may or may not help you build out your set up (and appropriately lighten your wallet, as I've discovered...). Plus, you're near Arches NP and Canyonlands NP, which also have plenty of hiking and scenic drives for cars.
Back to the trails: I've run several of the greens and while they're not technically challenging, they sometimes have some of the best scenery - Shaffer's Switchbacks is an amazing run. While the height and everything may look intimidating, it's a pretty easy run to drive.
