Answer: 'it depends'
Recommendation: You should absolutely pull off (plenty of room), d/c, and drive back there and look for yourself.
First, there is a lot of room out there. There is a pretty smooth and wide dirt road that goes straight back. There are offshoot .... roads may be a generous term ..... where you can pull in and find a spot. I had no problems in one of the first spots with my 47' 5th DRV. However, if I'd gone to the end of the trail, they would have needed a helicopter to get my rig out. Rutted, pitted, narrow and no way to turn around.
My information is 2 years old, and I know that it *all* depends on how the spring went. If it mudded up, and folks dug furrows trying to get out, you will be out of luck.
Wonderful place to set up shop. Sunsets are gorgeous, not far from the parks, or from town. Best of luck!
