We stayed there Thanksgiving weekend last year (2016). It's a very big site with lots of room for vehicles to move around. I didn't feel like there was a ton of room for tents, but that was based off of rocks and logs laid out at the site. I made adjustments and had plenty of room for my 4 person.
Getting there wasn't bad. I was in truck and had zero issues. We did see a car getting back there, assumingly to K-Bar 1, so it was possible at the time. There was a wash a little ways from the turn off which with the recent rains that have been hittin that part of the state, maybe worse, unless they maintained it.
It's a very open and free space. You're a good mile from KB-1 and way far from the road. Night time sky is like looking at heaven. It's amazing. The night also brings plenty of coyotes! And the morning sun coming up and shedding light on the Chisos makes for one of the best places to your morning "business", and enjoy breakfast.
