Am I in the right spot? Lol, i used the exact coordinates but hardly anyone is here. I asked one camper and he said he thinks this is correct however he was told it might be a mile from the original spot.
You could be in the right spot but... you are early. RTR starts on the 11th and you get 14 days of free camping on BLM land in any one location. Most folks that plan to spend the whole time at RTR won't show up till the 11th. If you are wanting to be there for the full 2 weeks it might be a good idea to roll out to another spot at least 25 miles away to wait till it officially starts. A bunch went down to Yuma to camp till it starts. Prolly a bunch up in Parker or Lake Havasu.
Also of note, those GPS coordinates are just slightly off. They'll bring you about 100 yards from the actual location. If you simply drive down that road (on the 11th or after!) you will see a sign for the RTR. It's easy to find.
