Question 1997 Thomas Saf-T-Liner - What's This - Roof Cover?

Recently purchased 1997 Thomas and have a few leaks in the roof. When up on the roof, I noticed this (see pic) vented cover. Its basically centered over the first row of seats. The "vent" was riveted on instead of screwed (which I believe how it was installed originally. Since it is slotted, seems like this is an easy place for water to enter the ceiling. Any ideas???? Thanks!

Remove it and patch it. I used the 14" piece of Lexan I cut out for the vent fan to patch mine.

I'd also like to know, I have one on a 1997 International 3600 Vista. It doesn't seem to connect to anything, just an open vent to the roof.

Ninja Edit: Thanks marc. Good to see there's nothing actually under it.

Anyone know what it';s supposed to be?

it's on 99% of bus bodies for positive cabin ventilation. Mine leaked too and someone repaired it at some point.

How does it vent with solid ceiling panels.? The only air that can get out of that 2' space is what comes through the 1" holes.

My IC has a single perforated roof panel in the drivers area. The rest are solid. I would guess some are equipped that way and the others itís just a dummy vent to let air in the insulation??
