You can get small vent unit thingies that the tiny home peoples use. You need them on the 20' container based designs as they are made from impervious stuff and all the condensation you breathe out has to go somewhere. What happens usually is the internal linings are permeable, so the moisture goes through them and hits the steel wall and stops and stays there which allows mould to form.

Yuck in a word.
