Vent on Roof
I have a 2008 Cardinal 30LE RK. All of the plumbing vents on the roof need to be replaced, you just have to touch them and they fall apart. While doing the job there is a vent in the back of the trailer almost 12 inches from the rear of the camper near the center. When I pulled it off there was no pipe coming up there was rubber roof material going across where the pipe should be. Then I noticed there was a patch of dicor. So I pulled that up and there was a slit about 3 inches long, I looked into the slit and there was a hole cut where a pipe should be I looked further into the hole and I could see insulation. Anyone know what this is for?
I did put dicor over the slit and put a new vent where the old one was. Just to keep it water tight.
