I stayed there for a couple of weekdays in mid-July, and was had the place largely to myself except for a fairly substantial porcupine that wandered through one morning.  The spots are well-spaced but most of them are pretty shallow, and not suitable for larger rigs or trailers.  I did see one large class C using the group camping area, which is basically a large parking lot with an outhouse and trash bin.  But, because many of the spots aren't great they look like they're not getting a lot of use (overgrown).  Still, the good spots are great and the campground is as tidy and well-kept as we've come to expect from BLM Alaska campgrounds.  Easy creek access!
