Where in Tennessee is your character from? If he's a city boy, then his wilderness survival skills might be low. But if he's a country boy, that's a whole other ballgame.
For all that people love to mock country folk and rednecks, they are extremely capable and imaginative, often overcoming problems caused by extreme poverty with grit, know-how, and very little to work with but whole lot of ingenuity. From experience living in small town deep South, these folks know how to track, hunt and set traps, to fix everything from cars to power tools to houses, they're handy with guns and knives and sometimes even bows, and they might ask their neighbor for a hand but they rarely if ever ask for true help from anybody. They're usually into camping, fishing, and almost any other outdoor sport you can think of, and they aren't sportsmen (though they do indulge); often they're bringing home food for the family because the grocery money won't stretch far enough.
While your Tennessee character may not know jungle survival, s/he may have a lot of skills that carry over, like setting hunting traps, skinning a kill, tracking a path, locating water, setting up lean-tos, dealing with snakes, etc. They may be able to make educated guesses on safe plants to eat and use some of their terrain knowledge to assist in finding shelter. It won't be exact, but while, for example, evading tigers may not be the exact same as evading mountain lions, big cats will still hunt in largely the same manner.
Now if s/he is a country kid, there will be equally common drawbacks--looking down on the highly educated or intelligent (especially if big words are used), prejudices about specific areas (people from the big city are snobs, California is full of hippies, Yankees are still a hated thing, etc), some insanely conservative opinions, deeply religious (which could not matter or actively hurt the group, depending), and a sort of xenophobia that leads to extreme pride of home and suspicion and even hatred of outsiders, including racism.
Also, possibly not a lot of education about sex which may effect your character's background. Teen pregnancy and early marriage (or at least a semi-permanent engagement until grown) occur more often than you'd think. One of the small towns I was in, looking at anyone over 13 could get you trouble, because all of them were married or engaged to be so, and many of the girls were mothers. It was considered normal, which was why they chased even the whisper of sex-ed out of town. And lets not forget the rare, hyper-religious kook who'll force their child to marry their rapist (I think one was an eight year old girl with her 30+ teacher) which is still prominent enough one Southern state recently struck down a law against child marriage because it took away parental rights.
Male or female, your character may well be a parent, or have a miscarriage or a short lived (or ongoing, because divorce is wrong) teen marriage in their past.
Unless they're city slickers, in which case they'll be much like other city slickers, except for some conservative opinions (though nowhere near as bad as the country), a love of country music, and a respect for education but still a lingering suspicion of the highly educated (doctors, scientists, etc.). Oh, and they might also have a thing about Yankees.
