I do know scouts did backbacking through the Davey Crockett national forest along the 4 C hiking trail,
and there were designated hunting camps. Parts of the park were closed so check first

Most of the scouts start near Ratcliff Lake seems like the stop was Walnut Creek campsite that had pads and a pit toilet, try the hiking threds on this forum, some of the members know that area well.
I don't hunt but do hike (much shorter hikes now)
