That's EXACTLY what I have in mind for the last few days. The idea of "camping" (going back to your camp for the night) is great. It's not 100% realistic (in RL people could kill you while you sleep), but it's better solution for other non-realistic shit. In real life you would guard the tent, sleep there, make shifts with your fellows, etc. You CANNOT do it in the game, because, uh, it's just a game and one's got to work :)
