My suspicion is you'd be fine - we did it with a 2007 Nissan Frontier. There were a couple spicy sections, but nothing that ever made me think 'fuck we're not going to make this', just like 'bah this might take a minute'.

YMMV, but it wasn't terrible

Also did it in late 2019, so plausibly things have changed since.

When I did WRT, it snowed the night before we ended and some dumbass tried to drive their corolla down the western end, couldn't do it, and just abandoned the car blocking the road.

We and 2 other groups pushed it into the ditch so we could get past.

Don't drive down a steep, one-lane, janky-ass road in a corolla.

Trying to 1-day it, multiday unsupported, or supported multiday?

The riding isn't all that spicy, for the most part. It's an old road, and still drivable (with decent suspension), but I'd be reluctant to do it unsupported on something that old. If you've got the option to just throw it on the jeep / a full repair kit, though, then sure!
