We used to pull horse trailers in there all the time - 20 years ago
We won’t be pulling anything in there again. Gained some plumbing experience due to large “pot holes” that can swallow trailer tires whole.
Forest service has forgotten about the road and let it fall into dismal shape. Would be best if traveled without a trailer and with 4x4.
Campsites are there but grasses have overgrown most of the site.
Assume that road is in poor shape and sites are best for tents.
