My rig is 31' and we did ok. There were a couple sharper turns on the dirt road after you pull off the highway. I did see a class A parked down there that was likely around 40'. Fortunately, the dirt road is a relatively short distance to the camping spots once you turn off the highway so I would recommend parking the rig and get out to scout the road first. It's a great spot.

We went with a 30 ft C-class. Rugged paths down to where one could camp. There were folks living fulltime there taking up the easy access spots. We now have a 45 ft Toyhauler. I would not take my rig there as there are no turnarounds large enough to accommodate our size rigs.

There are only a couple of spots big enough, and turning around would definitely be difficult unless no one else was already parked in the area. We pulled a 23' TT in and it was tight.

I don’t think it would work out for you. Really no place to turn around.
