I have no idea as to where this park is, so I can't give a specific suggestion. However, you might look at the website that has federal campgrounds such as the US Army Corps of Engineers parks, of which there are many in TX. You can see pics of the campsites and find out exactly what types of hookups are available, and you can reserve specific sites through the website.
We use the campgrounds at Granger Lake (about 90 miles from C.S.) and have been happy with them. Most have a covered table on concrete pad, and water and electricity.
I'm at work right now, so I don't have the website, but you can practice your Google-fu and find it easily.
