Gee, we had a different experience when we were there a couple weeks ago and loved our stay. We arrived on a Friday and the CG was full, so we stayed one night at Sully Creek State Park one night and returned on Saturday to find they had two sites available for our week stay and the CG was full most days of our week stay. Not sure what you mean there is no dump, unless you are referring to a dump at the site The CG info on the website indicates they are dry camping sites with no hook-ups and most national park CG's are either first come first serve and/or reservation. They do have a decent dump at the exit though and there were water spigots a plenty through out the campground. While I saw some big rigs in the CG in sites that looked plenty sufficient, as an example there was a 40' plus motor home in the site next to ours with easy access in and out, though some of the spots we saw were tight for big rigs. While we have a truck camper so getting in spots is rarely an issue, the very nice CG hosts at check in offered to let us drive by the two CG sites available before paying to see if either would work for us which we did. Maybe it was just me but for $14.00 a night, $7.00 for us with the senior citizen discount, I thought it was great value.
