Leak in Gray Water Tank
2013 Palomino Columbus 365 5th wheel. I have a leak from the top right corner of the gray water tank. I have removed the insulation and bottom cover to expose the tank. The exact location of the leak is not visible but I suspect it is coming from where the top and the bottom of the tank are sealed together. I would appreciate any information if someone has had a similar problem and been able to fix it. I am the second owner and do not have a warranty.
