I have just got a 2003 arctic fox that has a hole in the top of the fresh water tank. any idea what it takes to replace it? does not look like its going to be easy to get at.
My guess? THe prior owner probably thought "How do I reach in there and clean the tank? Then got out a hole saw, and you now have a easy wash tank system. That leaks when going around a corner. Opps!
You might be able to get a 12" square patch, and glue it over the hole. Or O-ring and screw down the patch, so you can remove and clean again?
