Can I suggest a short cut to all the rigmarole that comes with trying desperately to get sims to place those objects 'in the world' correctly? Drinking a moodlet solver will keep your sim happy and perky for another round of temple exploration without needing to worry about needs. Maybe not as much fun but I am rather a pragmatic simmer.
If you don't want to waste your satisfaction points on a moodlet solver then a camp bed and a cooler chest is really all you need. Your sim can sleep and eat, if you really want to get fancy then the Waterfall in a Can will clean them up a bit so then they can just pee in the bushes that are dotted around the jungle, have a shower from the can, eat and get cracking on their adventure again!
I have a wee trick, which mind you is a kind-of cheat but if you have a sim who likes fruitcake then you are made. Fruitcake never spoils and gives a happy+2 4hr moodlet as well as mostly filling hunger. if you pack it into a packed lunch before they eat it it gives your sim another positive moodlet. Whether or not a sim likes fruitcake is decided at their first bite so you can manipulate this by saving your game, directing your sim to take a piece and then quitting without saving if they hate fruitcake. Then reload and direct them to take a piece again...quitting and restarting until they like fruitcake. In all my 'for fun games' I do this so that my sims never have to go without food when away from their home lot, by choosing the Dance Machine trait they can also Disco Nap which fills the energy bar quicker than the L10 beds and they can nap on park benches, beds and even chairs if very tired. It's my way of avoiding the boredom of having to watch my sim eat for ages and sleep for a whole night, leave more time for actually playing the game.
