Great info, thanks. I tried it in my awd van 2 years ago. Didn't seem so bad then. Its probably worse now with all the new influencers trying to get out there.
I went there 2 days ago and it's pretty rutted. I had issues with my GX470 rear air bags and lost clearance and had to turn back halfway up the 2 way uphill section. You will need a lot of clearance to make sure you can ride out the bumps and keep momentum. Nothing technical just have to make sure you don't stop and keep momentum.
