This is a pet friendly campground around a square park right on 40. They have electric and non electric sites, but the majority were electric (and cost more). This was advertised $15 - $20 but the prices online were $38.50 for an electric site for one night (granted, it was a Saturday in August). There were not pet fees. There were lots of spaces available when we visited.
There is no office here, you pay for your rental online or on an iPad in the kiosk (if working). There is WiFi at the kiosk, but it does not reach many of the campsites well.
Sites are close together but level. Felt safe and it was quiet at night save for occasional passing cars. No fire pits or individual picnic tables, but there is a shared covered picnic area.
Clean bathrooms. Showers were more of a 2.5/5. Not super clean and water smelled rusty. Water from sink was fine though.
Morning became very busy with travelers stopping to use the public restrooms, which may help you decide where to park.
