We have driven up there and towed, but not camped. We pulled in to one to check it out, but would have to look it up. Have you checked Campendium for reviews? This is a super site with often photos and personal reviews. It's worth a check.
Note - just checked Campendium - all three are up there. The only one without photos, but with a review, is Boulder Park.
