Drove in on upper road. No evidence of snow. Took 45min from Marble, probably since we didn't encounter any oncoming traffic. Hit skid plate once on a rock at the far side of a stream crossing.
Drove out on lower road since we picked up 2 hikers and I didn't think the stock Trooper had enough power to get that load up the switchbacks. Only had an one issue with an oncoming fullsize Tundra that took some time to jocky around. I didn't think there were any difficult obstacles to worry about (other than oncoming traffic). Might scrape some branches on your side.
Neither road is bad as far as 4wd roads go. If you don't mind Baldwin Gulch rd, this one is easier.
