Nice looking hunt camp by the way, but a word of caution about propane stoves and heaters, they can kill you with the carbon monoxide so put in a monitor, they're cheap and don't forget a fire extinguisher.
That was going to be my advice as well. On my grandad's farm we tore down a 'bacca house (tobacco drying house) and built our cabin on the foundation. No power (except a generator) and no water but we did have an outhouse (until a tree fell on it). Insulation and wallboard will go a long way to making it more comfortable.
PS Don't leave any clothes there, even in rubber containers, mice will get in and eat holes in them.
