The sites were fairly level gravel sites, but as others stated, the sites are very close together.  

The only issue I had was the hookups are oddly close to the front of sites for a back-in site.  Not an issue for us since we have a shorter Jayco 174BH, but we had to park it so the hitch was just off the road.  The only reason this works is because they have plenty of parking, so once you place your trailer, you can then park your vehicle across the road.

We used the 30 Amp connection, and the sewer connection.  One of the things I disliked about the connections(other than the location being very far forward on the site) was the sewer connection was odd to me(first time having sewer connection at my camp site).  It was a pipe that stuck out of the ground about 6 inches with a 90 degree elbow on the top.  I don't think we spilled anything, but it did not allow our tanks to drain out of the hose until the end of the stay when I had to manually lift the hoses to evacuate them.

For the RV sites, each one is listed as XX feet off the highway, but there are plenty of trees between the highway and the camp sites to buffer then noise.

There are clean bathrooms and the showers require a token.  Didn't use them, just noticed it.  I mention this because you have to purchase the tokens and wasn't sure if they have to be bought during business hours or not?  So be aware of that.  The restrooms were clean and functional.

We have Verizon and had no issues with services at this campground.
