In addition to the above, Davisdale Conservation Area just west of Rocheport(MM 178) allows primitive camping similar to Hart Creek Conservation Area west of Hartsburg(MM 154). In Hartsburg, the better option is to stay in town at the city park mentioned above. The Hostel in Tebetts(MM 132) does cost $5/night but it is unmanned and noone is going to care if you stop there to get cleaned up as long as you don't make a mess yourself. It is normally locked, but the key is located on a utility pole on the east side of the building.
Another hiker that was on here a few years ago camped at the city park in Rhineland(MM 105). It has water, restrooms, and picnic tables and is located just north of the trail west of the ballpark. Marthasville(MM 78) allows camping at the city park. It is located south of the Katy and you camp on the other side of the street near the ballpark. I think they charge if you want to use the showers but other than that it is free.
