Are the tent sites disconnected from the parking spots or are they separated by cement barriers. Would a tent that attaches to a vehicle work in the tent sites?

The tent sites I saw were disconnected from the parking spot. We have a pop-up tent trailer. Our site was a pull through but was not very level and had a short space that could barely fit the truck. It was also very dusty, so investing in some oxyclean might be a good idea.

the spot I stayed in two weekends ago had a small post about 12" tall between the parking spot and the camping area. the picnic table was about 8 feet back of the post
