There are many sites off this road, but it was extremely crowded when I went in April. Additionally, the sites are quite close to another nearby main road that is primarily parallel to the road you camp off. I didn’t hear much car noise from that road, but I could easily see the cars driving by from my tent. With these things in mind, I wouldn’t necessarily say I felt isolated when camping here in my tent, and it is definitely not “out there” in nature, though the views of the Organ Mountains are wonderful.
The road in is very bumpy/rocky. I’m a risk-taker with my Toyota Corolla and was able to make it the full way from one end of the road to the other (driving VERY slowly and carefully), but had to get out of my car multiple times to move large rocks out of the way.
In all, I recommend this spot due to the beautiful views and convenient location, but be aware that it might be pretty crowded and the road doesn’t necessarily suit normal cars (shout-out to my fellow non-camper/van/jeep risk-takers!).
