What is your touring setup? Are you on an actual road bike, skinny 700c tires? Or on an actual touring bike? Are you using panniers, or a trailer, or both? What is you touring experience?
To others not super familiar with bike touring, every kind of road from the north pole to the south pole has been ridden with a full load. Not neccesarily a Burning Man load though. I totally agree the roads there aren't great, and are heavily traveled, but it can definitely be done if you have the right setup.
FWIW, to anyone touring there, I will gladly open a conversation with you about how I can help out or support in any way!!!!
