I finally got around to looking at our tank, and discovered there is a sheet of some kind of plastic between the metal tank and the metal bulkhead to which it is bolted. I didn't get around to unbolting the tank today, but I snapped a couple pics trying to show the plastic sheet. Has anyone else run into this stuff? I'm hoping the plastic may have prevented the heavy rust found on other coaches, since it prevents metal-to-metal contact between the tank and the bulkhead. Once I get the tank pulled loose, I will report back.Don't know if the photos really show the plastic... It is "sandwiched" between the tank and the bulkhead, and held in place by the tank mounting bolts.Going to check ours in the morning....I recall seeing the same thing..... Quote Selected
