Black water Vent issue
This week end I went to replace the black water tank vent cover, because the "hat" was missing. The area around the a the vent tube was full of dirt. I noticed some deformation towards the curbside of the roof, as you can see in one of the attached picture. The roof area around on under the vent cover was not sealed as you can see in 1of the pictures. The deformation seems to be from water getting under the roof covering. By feeling the area it seem the roof cover is still attached to the top layer of plywood and bond between the plywood layers has failed because of the water intrusion from the vent area! The vinyl roofhas not been conpermized. I have come up with 2 possible ways to address the deformation. 1. Install a piece of stiff vinyl over the area. 2. Inject some wood glue in the area, then apply some weight while the glue sets up. I guess a 3 thing would be to do nothing, just monter the area.
