Does anyone know if the waste water pipe that vents through the roof has a cap on it? Does anyone have any pictures of what this looks like or know where a replacement can be bought?
Here's a thread that walks you through the repair - http://www.airforums.com/forums/f163...nts-24437.html. The pictures should answer a lot of your questions. This is a vent pipe for the sewer system. Your trailer may have one or two. The actual business of preventing water from running down the inside of your shell is accomplished by the black rubber membrane and good (not silicone!) caulk. vintagetrailersupply.com or Inland RV are common sources for the stack cover if that needs to be replaced. My old Argosy covers were sun ruined plastic that fell apart in my fingers.
