I have noticed that some WB's mine included have vents in the coach roof, was this a later upgrade, or did some owner just cut holes in them? I have taken the old ones on mine out, and have stripped the wooden spacers/supports off as well, as they were badly cracked, and damaged beyond repair. The problem I now have, is trying to find a suitable replacement that will take the shape of the coach roof. I love the Vetus Mushroom Vents, but some how I don't think they will work. http://www.gaelforcemarine.co.uk/38031/Vetus-Mushroom-Ventilators.html?referrer=FROOGLE&gclid=CKiWsIGb5r4CFSGWtAodBkQAGA.
