The vents can also keep the underbelly from completely filling with water if you have a leak, causing the liner to pull loose and crash down before you even know you have a leak.
We have a vent like that right under the bed area of our 5er. It alerted us to a small leak under the shower,,only dripped once every 2 minutes or so...repaired last month under warranty.
I'm actually happy to find those vents; leak alert and humidity prevention
