It's not set up for MHP. It looks like someone started setting up a campground, but didn't finish the project. There is a nearby building that could potentially have a restroom, but it look like it hadn't been used in a couple of years.

There was a sign that said "Sheffield Camping" and they have a listing on hipcamp https://www.hipcamp.com/en-US/land/texas-sheffield-camping-dw9hd96r
