We recently spent 4 nights here, along with about 10-15 other camping vehicles, ranging from a Toyota Camry to 5th wheels and horse trailers.  Easy access for our 39ft class A and toad, but it was busy around 2pm when we arrived and filled up even more afterward.  Every day a few spots opened up by 10/11a but filled by 5p.  There were a couple of port-a-potties, if needed.  The camping site is actually bumpier than the gravel road coming in. Not much noise, considering proximity to highway and other campers, surprisingly.
