You missed Davis Mountain State Park. It is just outside of Ft Davis - even has a Ft Davis mailing address
They have about 100 sites of which 27 full hookup sites with cable tv even, for only $25 a night. We stayed there for a week. Lots of animals in the campground.
I would stay there I know Prude is just an open field - The Fort Davis Inn is right on Main St and very small. Its advertised rates are more than the state park
We used to live next to you in Richardson TX, I hope DS is prepared for how small fort davis is and how remote. They do have one grocery store.
