@Celticrose67 You could try locking the other trailers doors for Everyone while empty. But it doesn't always work though on a home lot, in particular I've found if you travel and return they may be in the locked area and you'd have to unlock it to let them out. I've also found them wandering in to wash dishes and ignoring the locked doors.
But now I see it mentioned the roommate idea may be just what you're looking for if you do have DU, I've only used it playing as a dorm roommate and didn't like that my Sims couldn't sleep while the roommates were moving around and they wouldn't stop cooking. But that may be worth a look to see if it works better now. I kind of gave up on it after one try, I should really try it out again as it's been a couple of years.
I'd also advise adding the fire prevention system and not just smoke alarms too. Lately I've found if Sims not under my control are cooking/using BBQs they may cause a fire. (Just had a whole load of houseguests cause chaos). So if you add sprinklers that should help, as well as saving your game regularly.
I forgot to mention too, to add extra income you could always add a few plants with harvestables. Maybe like a little allotment. Harvesting them to sell each day would earn more money, as would fishing if you're near water. I quite like the idea of a little trailer park with a vegetable garden/flower patch. I vaguely remember I had one in one of the Sims 3 games now I think back, with a big lake.
What @PipMenace said. I’ve used the roommate system and had elaborate locked doors (lock door for everyone but roommates, lock door for everyone but household). You still own and are taxed for the roommate’s furniture, though.
(Honestly, I mostly use the roommate system to live with the RoM Sages without breaking them.)
Hi
Thank you for answering, i'm definitely going to give the roommate system a try 🙂
