We stayed here for a few nights in the Sandpit campground loop.  Most of the campers there had ATV's.  

The bathrooms and showers were good.  Clean and plenty of hot water. 

There is also a West campground loop that caters to RV use more but it gets filled up fast.  

It is a decent location for visiting Zion and other national parks and St George.  

Overall, we were not excited about this campground, but it was adequate.  We had water and electricty hookup.  Many sites do not have electricity and people used their generators.
