We've stayed here twice now. Once in a huge 36 ft toy hauler and now in our 26 ft Class C RV. It's a long dirt road that has a few big bumps, but if you're going slow it's passable in almost any vehicle. There are 13 official camping spots with plenty of room to accommodate a big rig. However, it's important to send a tow car down there to scout there is very little room to turn around at the end if all spots are full!  Super quiet with beautiful views overlooking the Mesa. About a 5 to 7 minute drive to the visitor center.
