I do not know where the true campground is for this spot, but if you go to these coordinates it is only a parking lot for a trail head. There are NO vehicle entrances.

I believe the correct spot is

“West Gate to Bulldog Canyon OHV Area” which is less than a mile NE from here. This area has gates that are locked sometimes but the parking lot is much larger and you can fit an RV there.

Keep in mind there is a shooting range about 1.5 miles from both of these locations and there is a lot of traffic at night. It doesn’t bother me, personally, but if you are prone to PTSD or have trouble sleeping, I recommend going somewhere else.
