Absolutely no problem getting to the end of the road in my stock 4runner, buddies stock taco made it to, A few sections of the road may be susceptible to washouts in the next big rain storms as there was some signs of slope instability above and below some sections of the road. 60ish water bars between the deactivation sign and the TH at the end of LE12000 branch, I dragged my hitch on one of them.

Recently reshaped by logging company: numerous moderate waterbars, easily passable by high clearance 4WD. Sign at km 7 says 4WD only. firm solid and graveled. Drove up to km 12.2 then turned onto access Liumchen trailhead.

Gate at 7 KM appears to be on a spur, but sign made it seem like the mainline was blocked.

First 5km are well-graded and about as nice an FSR as you can ask for. After that things get a bit steeper and occasionally looser with regular cross-ditches, but nothing too demanding. There are a few tight spots around fallen rocks and trees with pin-striping opportunities that a smaller vehicle could probably avoid.

No major washouts on this road, just some cross ditches to go though. Most are quite small, but some steeper ones closer to the top. I scraped the hitch on 2 with my 19* departure angle and being careless. Something like a rav4 should be no problem. Road was super dry and dusty and clear of snow. Quite popular with dirt bikes so something to be mindful of. Road partially blocked at the junction with LE12000 or 12.25km.

Drove all the way to the Liumchen East 12000 spur just fine in a 4x4 with reasonable clearance (Jeep Cherokee). Lots of cross ditches but nothing huge, no gate that we saw. Snow stopped us going further but we did hike the spur and I saw nothing that would stop you reaching the end once the snow is gone. Doesn't require 4x4 but high clearance would be nice, an SUV may scrape at times
