I just moved into a new single wide trailer and there's this switch in the utility room labeled 'Whole-House Ventilation'. It's a bit confusing because it seems to only activate one fan in the room. Can anyone explain what this switch is actually doing?

It sounds like that fan might actually be venting outside. When you turn it on, it could be designed to pull in cooler outside air if you have your windows open. This helps exchange the stale, warm air inside for fresh air from outside, especially useful during cooler times.
Yeah, I can relate! We installed a similar system in our older home and it really helps cool things down when the outside air is cooler. Just make sure to crack those windows!
